Democratic presidential hopeful Bernie Sanders Bernard (Bernie) SandersBiden rallies Dem support for progressive Md. governor candidate Ocasio-Cortez: Democratic socialism is 'part of what I am, it's not all of what I am' Divided Democrats are in danger MORE said on Sunday that he takes issue with the idea of superdelegates. 
  
 "The whole concept of superdelegates is problematic," he said on CBS's "Face The Nation."

 The Vermont senator said he thinks it would be a good idea for superdelegates to come over to his side in states where he has won by a significant margin. 
  
 "I think it might be a good idea for superdelegates to listen to the people in their own state," he said. 
  
 "I just talked to a person the other day who said, 'You know what? I am going to listen to my state, and if my state votes for you, Bernie, you're going to have my vote.'" 
  
 Sanders said that's something he hopes a lot of superdelegates take into consideration, adding that it's "common sense" to listen to the voters. 
  
 The superdelegates have the right to make their own decisions, he said, adding that the primary objective is making sure a Republican does not win the White House. 
  
 "[If] it appears that I am the stronger candidate against Trump, I think you're doing to see some superdelegates saying, 'You know what, I like Hillary Clinton Hillary Diane Rodham ClintonOcasio-Cortez responds to Dem senator who said policies 'too far to the left' don't win in Midwest July vote to repeal medical device tax may bolster vulnerable GOP lawmaker Rosenstein conflicts undermine legitimacy of Mueller's investigation MORE, but I want to win this thing. Bernie is our guy.'" ||||| Is this just another case of the Establishment sticking it to the people, or legitimate frustration with a gadfly who won’t wake up and smell the coffee? Bernie Sanders’ colleagues in the Senate want to sound supportive, Politico reports, mindful of the anger of the populism that has allowed the longtime socialist crank to seriously contend for their party’s presidential nomination. They love Bernie. And more precisely, they’d love him even more if he got on the Hillary Clinton bandwagon: 
  
 After holding their fire on Sanders for the better part of a year, the senators — all backers of Hillary Clinton — are gently calling on Sanders to face the reality that there’s almost no chance he’s going to be the Democratic nominee. They don’t say outright he should quit; doing so would be counterproductive, they say. But nearly a dozen Democratic lawmakers suggested in interviews that Sanders should focus more on stopping Donald Trump and less on why he believes Clinton’s stands on trade, financial regulation and foreign policy would make her a flawed president. “What’s important is not whether or not he gets out, but how he campaigns,” said Sen. Claire McCaskill (D-Mo.). “If the contrast is now about what separates us from Donald Trump, then I think it’s fine. I just hope that we can begin to focus on unifying because obviously a lot of us are perplexed that we could be facing a country led by someone who seems to be a buffoon.” Added Sen. Jeanne Shaheen (D-N.H.): “It’s good [for Sanders] to continue to raise the concerns that people have, but I think it ought to be in the context of, ‘This is the difference between the Democrats and Republicans in this race.’” 
  
 Or, in other words, keep campaigning … but for Hillary. 
  
 This request isn’t so much a party establishment putting down its considerable foot as it is a cold dash of reality. Hillary already has two-thirds of the delegates she needs for the nomination, while Sanders would need almost double what he currently has to win on the first ballot. The problem for Sanders is that Democrats have gone through half of the states already, and at least some of the delegate-rich states left on the table will go to Hillary — New York and Pennsylvania for sure, Kentucky and Indiana probably, and California more than likely. 
  
 Even in states where Sanders competes well, close races will split delegates too narrowly to help, such as the upcoming Wisconsin primary. As Paul Begala pointed out in the aftermath of Super Tuesday II, Bernie wins the tight races and Hillary wins the blowouts. That produces an inevitable delegate-allocation gap that Sanders can’t overcome. 
  
 Ah, but what about the superdelegates? Absent the superdelegates, Hillary only has a lead of around 300 delegates — a difficult gap to bridge, but not insurmountable. Superdelegates can change their minds and flip to Sanders, right? Sure, but that won’t happen. Superdelegates exist to prevent candidates like Sanders from seizing the nomination from the party establishment. The reason it didn’t work in 2008 was that Barack Obama got too big of a lead on Hillary, and the historical moment and organizational power of Obama convinced the superdelegates to throw in with him in the end. (Recall that the question of the superdelegates ran almost all the way down to the convention in 2008.) 
  
 The Democratic party establishment is right on the math and on the moment this time around, but don’t expect Sanders to listen. He’ll keep campaigning until the cash runs out or until the DNC cuts him some sort of deal. Perhaps Hillary will offer Sanders a Cabinet post, such as HHS, where he can indulge all of his single-payer healthcare fantasies if Hillary wins the election. The deal will probably come sooner rather than later, but it may take a couple of more major-state blowouts to get the message through to Bernie that it’s over … and it’s been over for a while. ||||| Democratic senators of all stripes are as impressed as they are surprised by Bernie Sanders’ insurgent campaign. 
  
 But the time has come, they say, for Sanders to start winding things down.

 After holding their fire on Sanders for the better part of a year, the senators — all backers of Hillary Clinton — are gently calling on Sanders to face the reality that there’s almost no chance he’s going to be the Democratic nominee. They don’t say outright he should quit; doing so would be counterproductive, they say. 
  
 But nearly a dozen Democratic lawmakers suggested in interviews that Sanders should focus more on stopping Donald Trump and less on why he believes Clinton’s stands on trade, financial regulation and foreign policy would make her a flawed president. 
  
 “What’s important is not whether or not he gets out, but how he campaigns,” said Sen. Claire McCaskill (D-Mo.). “If the contrast is now about what separates us from Donald Trump, then I think it’s fine. I just hope that we can begin to focus on unifying because obviously a lot of us are perplexed that we could be facing a country led by someone who seems to be a buffoon.” 
  
 Added Sen. Jeanne Shaheen (D-N.H.): “It’s good [for Sanders] to continue to raise the concerns that people have, but I think it ought to be in the context of, ‘This is the difference between the Democrats and Republicans in this race.’” 
  
 The subtext of these comments is the general view among Democrats that Sanders has no path to win. Clinton has nearly double the number of delegates that Sanders has, and she swept the Vermont independent in three distinct regions of the country last week. 
  
 “It will be almost impossible for Sen. Sanders to catch up. And he should do the math and draw his own conclusions,” said Sen. Barbara Mikulski (D-Md.). 
  
 “The writing’s on the wall,” said Sen. Barbara Boxer (D-Calif.). 
  
 The message senators are airing publicly mirrors what President Barack Obama told donors in private recently, according to The New York Times: That while Clinton may have her faults as a candidate, the party needs to channel its energy into defeating Trump. 
  
 Over the past month, Clinton campaign staffers have bristled at the way Sanders is running. A Clinton campaign memo said Sanders has been “increasingly negative” and accused him of breaking his vows not to name Clinton in his ads, blaming his sweeping losses on a negative strategy that “backfired.” 
  
 While tame compared with the accusations of lying and name-calling that dominate the Republican race, Sanders has gone after Clinton more aggressively of late. In the run-up to the Illinois primary, he highlighted her ties to Chicago Mayor Rahm Emanuel, who’s unpopular among African-American voters and distrusted by progressives. And Sanders has repeatedly dismissed Clinton supporters as part of the “establishment,” which Democratic senators interpret as showing disrepect for them. 
  
 Still, Democratic leaders say they’re confident Sanders will do the right thing in the end. As pointed as some of his barbs at Clinton have been, they argue, the self-described democratic socialist hasn’t gone overboard. 
  
 “Bernie is a very constructive person. And he wants to move American politics closer in his direction. He’s done that already,” said Sen. Chuck Schumer of New York, the expected next Democratic leader. “I am not worried.” 
  
 The Sanders campaign dismissed any suggestion that it’s time to wrap up his long-shot bid and pivot to defeating Trump and the Republicans. Campaign spokesman Michael Briggs insisted Sanders is still a superior general election candidate because he “consistently draws much more support than she does in general election matchups with the Republican front-runner.” 
  
 “If Democrats are interested in holding on to the White House, if Democratic senators are interested in regaining a majority in the Senate and picking up seats in the House and statehouses all across the county, Bernie’s the best bet,” Briggs said. 
  
 Even so, Democrats privately believe Sanders is already calculating how to gradually shift toward a posture of unity by summertime. With Clinton favored to win the nomination and beat Trump in the general election, Sanders also has to think about his relationship with a potential future president and returning to the Senate, where he caucuses with Democrats. 
  
 “He won’t do it,” said one high-ranking Democratic staffer on Capitol Hill of Sanders continuing to attack Clinton in ways that go beyond their policy differences. 
  
 At the same time, Democrats need to tread carefully in how they treat Sanders. His legion of followers will be critical to getting Clinton elected, not to mention scores of Democratic Senate and House candidates. It’s unknown how hard Sanders would campaign for Clinton, assuming she does prevail. 
  
 “I think that Sen. Sanders has built a movement. And that whatever happens, the two big tribes of the Democratic Party will be able to unite at the convention and be so much stronger,” said Sen. Brian Schatz (D-Hawaii). 
  
 But the dance is sure to be awkward. Not a single Democratic senator has endorsed Sanders. And beneath their deference, there’s growing irritation among the lawmakers that the longer his campaign continues, the more he will undermine Clinton in the fall. 
  
 “That’s something he’s going to have to decide,” Senate Minority Leader Harry Reid (D-Nev.) said of how long Sanders remains in the race. “She’s going to be the nominee.” 
  
 But, for now at least, Democrats believe measured diplomacy is the best approach for dealing with Sanders and his supporters. 
  
 “I don’t think any Democrat should call on him to get out,” said Sen. Sherrod Brown (D-Ohio). “Almost no Democrat I know would say that. And shouldn’t.”

Output:
Politico interviewed about a dozen Democratic lawmakers about the Bernie Sanders campaign and finds that a clear consensus is in the air: "The time has come, they say, for Sanders to start winding things down." The general view is that he can't possibly win and that if he wants to stay in the race, that's OK—as long as he starts directing his fire more toward Donald Trump than at Hillary Clinton. Sen. Claire McCaskill is one of those quoted in the story, and her remarks sum things up: “What’s important is not whether or not he gets out, but how he campaigns," she says. "If the contrast is now about what separates us from Donald Trump, then I think it’s fine." The story echoes the sentiment behind a recent New York Times story that said President Obama has been privately telling donors that it's time to get behind Clinton so she can focus on Trump. Blogger Ed Morrissey at Hot Air sums up the Democratic viewpoint toward Sanders as "keep campaigning ... but for Hillary." And he thinks that party leaders are probably on the mark with the strategy. "Perhaps Hillary will offer Sanders a Cabinet post, such as HHS, where he can indulge all of his single-payer healthcare fantasies if Hillary wins the election," he writes. "But it may take a couple of more major-state blowouts to get the message through to Bernie that it’s over … and it’s been over for a while." Sanders, though, clearly disagrees. On Sunday, he began raising pressure on superdelegates in states he's won by big margins to respect the will of voters and back him at the convention instead of Clinton. The whole issue of unbound superdelegates is "problematic," he says, per the Hill. (The latest campaign finance reports had some surprise winners and losers.)
