Updated and corrected. 
 
 On a muggy Fourth of July night just outside Austin, Rep. Beto O’Rourke walked on stage wearing a light blue button-down, with a Texas-size American flag in the background. But rather than one of his campaign rallies in his Senate bid against Republican Ted Cruz, the Democrat was in front of the thousands that came out for Willie Nelson’s Fourth of July Picnic, an annual celebration of country music started by the legendary singer 45 years ago. 
 
 Met with a mix of wild cheers and a fair share of booing on the soggy holiday, O’Rourke explained why this Independence Day mattered even more to the country, expressing hope that “the big, bold, confident, strong people of the state of Texas” would help show the rest of the United States that there’s no need to be afraid of immigrants, Muslims or anyone else who might be considered different. 
 
 “It’s my honor to be here tonight, to be able to work with so many of you,” he said just before the fireworks, “to be with legends like Ray [Benson] and Willie, who ensure that in times of disappointment and darkness that we meet that with power and joy and rock-and-roll music.” 
 
 Soon after, O’Rourke, whose punk-rock roots would later be rehashed by the Cruz campaign, shed his button-down for a black T-shirt and guitar and joined Nelson and the rest of his band on stage for spirited renditions of “Roll Me Up and Smoke Me When I Die” and “Will the Circle Be Unbroken” to close out the show. 
 
 For Nelson, the jam session with O’Rourke was the latest in a career filled with activism and liberal-leaning political stances that have largely gone against the norm for country-music culture. 
 
 But for some of Nelson’s fans, his partnership with O’Rourke was the breaking point. After Nelson announced Wednesday that he would be headlining a Sept. 29 rally for O’Rourke in Austin, fans have taken to social media to boycott and publicly disown the country legend. 
 
 On Nelson’s Facebook page, where he posted an article from news outlet Austin360 with the announcement, some of the most striking remarks accuse the performer of aligning with what they believe to be the “socialist” positions of O’Rourke. 
 
 “Goodbye Willie,” David R. Williams posted on Facebook. “I don’t support socialist commies! You’re not going to advertise on my FB page either.” He added: “Like we say in Texas, Now Git.” 
 
 “Open your eyes Willie!” Claudia Kirby Heathington wrote. “Beto is a Socialist who probably has lied to you. This is a real shame you support him.” 
 
 “Wow what a let down,” Melanie Philip said. “You would pick a socialist agenda and an Anti American fellow like BETO, shame on you.” 
 
 One man was so disgusted with Nelson that he offered up his ticket to one of the legend’s upcoming shows. 
 
 “I am no longer willing to watch that hippie guitarist who supports that … socialist running for Senate,” Dakota Bell tweeted Wednesday.

 Others were much more supportive of Nelson and questioned those skeptical of the country legend. 
 
 “Not sure what went wrong in your life that would make you insult Willie Nelson,” tweeted Wheeler Walker Jr., a country singer and songwriter, on Thursday. “You can argue politics all you want but you cannot argue Willie.”

 In a news release announcing the concert, Nelson offered insight as to why he’s backing O’Rourke. 
 
 “My wife Annie and I have met and spoken with Beto and we share his concern for the direction things are headed,” Nelson said in the release. “Beto embodies what is special about Texas, an energy and an integrity that is completely genuine.” 
 
 The outrage comes as O’Rourke and Cruz are entangled in a tight Senate race, described by the incumbent as a “dogfight,” that has gained national spotlight in recent months. 
 
 Nelson’s political activism goes back decades, with his support of the environment, same-sex marriage and, famously, marijuana legalization. In 1980, President Jimmy Carter invited him to perform at the White House. Nelson later said that during the visit he smoked what he called a “big fat Austin torpedo” on the roof of the White House. He has supported President Barack Obama, Sen. Bernie Sanders (I-Vt.) and Hillary Clinton in recent years. 
 
 He even released a song last year inspired by President Trump, called “Delete and Fast-Forward.” 
 
 “Delete and fast-forward the news. The truth is the truth, but believe what you choose,” Nelson sings. “When we blow the whole world back to where it began, just delete and fast-forward again.” 
 
 Correction. The original version of this story incorrectly said this is the first public concert Nelson has held for a political candidate. The story and the headline have been corrected.

(Erich Schlegel/Reuters) 
 
 No doubt about it: Rep. Beto O’Rourke (D-Tex.) is a Democratic star the likes of which the party hasn’t seen in a Senate candidate in years. But is he too hot for the Democratic Party’s own good? 
 
 On Friday, his Senate campaign announced it raised $38 million in just the past three months. 
 
 That will go down in history. What O’Rourke raised in three months is what some presidential campaigns raise. It blasted through a fundraising record ($22 million in one quarter) that no Senate candidate has been able to touch in 18 years. 
 
 To put that money in perspective in Texas, $38 million was more than half of what O’Rourke — who was already raising insane sums of money — raised during the rest of his entire campaign. The $62 million he has raised so far is more than twice as much as his opponent, incumbent GOP Sen. Ted Cruz, has. 
 
 'It’s an astonishing number — and done with all people, no PACs," said Adam Bozzi with the End Citizens United PAC, which supports candidates like O’Rourke who have said no to political action money from special interests. O’Rourke’s campaign didn’t share much detail about his fundraising, but he did say the contributions averaged $47 from roughly 802,000 people, about half of whom were in Texas. 
 
 But that does not mean O'Rourke will win a Senate seat in Texas. He's still behind in the polls, and the fundamentals of the conservative state suggest it might not be ready to elect a Democrat to statewide office. 
 
 And if a fired-up Democratic base is so willing to pour money into big Senate races, you could argue that at least some of that money would be more useful going to fellow Democratic candidates in red-leaning states like North Dakota and West Virginia and Montana and Tennessee, all of whom have a much better chance of winning than O’Rourke does. 
 
 The Texas Senate race is still remarkably competitive. But let’s put this $38 million — and O’Rourke’s chances in Texas — in perspective. 
 
 He’s behind in the polls: O’Rourke hasn’t led in a single high-quality public poll since this race began. Some polls this spring and summer had the race too close to call. But since September, Cruz has been well ahead. A new Quinnipiac University poll shows Cruz ahead of O’Rourke by 9 percentage points, mirroring Republican private polling showing Cruz ahead. Polling closer to Election Day tends to be more accurate since more likely voters start paying attention. 
 
 Money can mean momentum, but it doesn’t always equal momentum: In 2014, Democrat Wendy Davis launched a buzzy run for governor in Texas. At one point she outraised her Republican opponent (though not nearly as much as O’Rourke is outpacing Cruz), earning her lots of national headlines and even more buzz. 
 
 She ended up losing the governor’s race by 20 points. It was the worst showing of a Democratic candidate for governor in the state in 16 years. 
 
 That’s not to say O’Rourke is going to lose as Davis did. But that a Democrat in Texas can raise tens of millions and still lose badly underscores our next point, that: 
 
 The fundamentals in the state still favor Republicans: There is plenty of evidence that Texas Democrats are motivated to vote in November — not an easy thing to do in a state where general elections are usually foregone conclusions for the Republican. 
 
 In this spring’s primary, Democrats doubled their turnout from 2014 to 2016, breaking 1 million voters. At the state level, Democrats are challenging Gov. Greg Abbott (R), 14 of 15 state Senate seats and nearly 90 percent of the state’s 150 state House seats. Texas Democrats haven’t put up that kind of defense in a quarter-century. 
 
 “The energy in the Lone Star State is palpable,” Democratic National Committee Chairman Tom Perez said. 
 
 But Republicans set their own primary vote record with 1.5 million votes. And they didn’t have to stretch that much to do it; 1.5 million votes was a slight uptick from the last midterm election cycle. Cruz got twice as many votes in his Republican primary than O’Rourke did in the Democratic one. And O’Rourke ceded 38 percent points to two much lesser-known, less-hyped challengers. 
 
 Democrats in Texas say that if the state votes like it looks (meaning minority and younger voters vote Democratic and vote in high numbers), it can be blue. But so far there’s little evidence that’s happening, at least to the degree Democrats need. 
 
 [Signs of the blue wave in Texas? Not so fast.] 
 
 There are a lot of other places this money might be more useful: One GOP operative calculates that what O’Rourke raised in three months is more than three times what Democrats have spent in North Dakota so far. It’s more than double what Democrats have spent in Tennessee and West Virginia. 
 
 Not every state is created equal, of course. It costs more to buy TV ads in Dallas than in, say, Fargo, N.D. But those three Senate races all have something in common that O’Rourke’s doesn’t: The Democrat is more likely to win. 
 
 Texas doesn’t even make the top 10 of the Fix’s latest rankings of the most competitive Senate races. Democratic Sens. Heidi Heitkamp (N.D.), Joe Manchin III (W.Va.), Jon Tester (Mont.), Bill Nelson (Fla.) and Democratic candidate Phil Bredesen in Tennessee are all on the list. Some of those candidates, especially Heitkamp, are fighting for their political careers. And their races are crucial to helping Democrats take back the Senate. 
 
 [Why is Heidi Heitkamp voting against Kavanaugh?] 
 
 Republicans to whom The Fix spoke couldn’t be happier to see so much Democratic money go into Texas instead. 
 
 “Every dollar that’s going to Beto," said one Republican operative watching the race closely and granted anonymity to speak candidly, “is a dollar that is not going to Florida or Montana or North Dakota.”
– A free Willie Nelson concert in the heart of the Lone Star State seems like something that would attract fans of all political stripes, but there's a good chance the Sept. 29 event will feature a largely left-leaning crowd. That's because the country crooner is headlining a "Turn Out for Texas" rally in Austin for Beto O'Rourke, the Democratic challenger to GOP Sen. Ted Cruz, and many of Nelson's fans aren't happy about it, KTRK reports. Per Austin360, it's "the first public concert Nelson has held for a political candidate," the singer's publicist says in a release, though Rolling Stone notes he's put on private concerts for politicians in the past. "My wife Annie and I have met and spoken with Beto and we share his concern for the direction things are headed," Nelson says in the release. "Beto embodies what is special about Texas, an energy and an integrity that is completely genuine." The site notes Nelson even brought O'Rourke out on stage during his Fourth of July concert. None of this pleases Nelson's more conservative fans, who see his ties to O'Rourke as a "breaking point," per the Washington Post. "I am certain you've lost your mind," one commenter wrote on Nelson's Facebook page, while another noted: "Willie's position is proof positive that marijuana use over time kills brain cells." Still others are dumping already purchased tickets to future Nelson shows. Many, however, applauded Nelson's decision. "So glad you are involved in this good cause. I have always been a fan, and am now a bigger fan," noted one well-liked post. The Post notes Nelson has long been politically active, throwing his support behind Barack Obama, Hillary Clinton, and Bernie Sanders, and advocating for pot legalization, gay marriage, and the environment.
