Q: Influential Republicans pledged Wednesday to support Christine O'Donnell's general election campaign after party leaders initially turned their backs on the Tea Party candidate following her upset win in the Delaware Senate primary. 
  
 O'Donnell's rise from obscurity to victory over longtime Rep. Mike Castle had sent Republican honchos in Delaware and Washington into a state of political shock. Aides for the top fundraising arm for Senate Republicans said Tuesday she would not be getting help from them -- a reaction that raised concern the party would torpedo its chances at a congressional takeover out of spite. 
  
 But National Republican Senatorial Committee Chairman John Cornyn said in a written statement Wednesday that O'Donnell would have NRSC support as well as the maximum $42,000 donation from the organization. 
  
 "Let there be no mistake: The National Republican Senatorial Committee -- and I personally as the committee's chairman -- strongly stand by all of our Republican nominees, including Christine O'Donnell in Delaware," Cornyn said. 
  
 Castle, who argued O'Donnell could not win in a general election against Democrat Chris Coons, reportedly will not endorse O'Donnell. But party leaders on Capitol Hill tried to embrace her candidacy Wednesday. 
  
 Senate Minority Leader Mitch McConnell, R-Ky., told Fox News he would support the nominee and donate money from his political action committee. 
  
 Republican National Committee Chairman Michael Steele announced his support. 
  
 Rep. Mike Pence, R-Ind., the third-ranking Republican in the House, said he would not count out O'Donnell in November. 
  
 "I categorically reject that Christine O'Donnell cannot win in Delaware," he said. "This is a whole new world. We elected a Republican in Massachusetts." 
  
 O'Donnell's win posed one of the biggest upsets to the Republican establishment this year -- a campaign season marked by a series of outsider Tea Party victories. Republican leaders ultimately came around to candidates like Sharron Angle in the Nevada Senate race and Joe Miller in the Alaska Senate race, where incumbent Sen. Lisa Murkowski was defeated in the primary last month and has not yet decided her next move. Cornyn pointed out Wednesday that the NRSC also just aired its first ad in support of GOP Senate nominee Rand Paul, a Tea Party favorite, in Kentucky. 
  
 O'Donnell, though, was a perennial candidate with no government experience and a history of personal financial problems. Delaware Republican leaders had condemned her candidacy and offered few words of encouragement after her victory over Castle by a 6-point margin. 
  
 Republican strategist Brad Blakeman said the initial move to alienate O'Donnell was poor strategy for Republicans looking to take over at least one chamber of Congress in the fall. He said the party needs to unite with all the Tea Party-backed nominees before November or risk not only losing seats but the possibility of the Tea Party defecting into a bona fide third party. 
  
 "We're not going to like every candidate 100 percent," Blakeman said. "You need to regroup now. ... The risk is you're going to blow apart the Republican Party." 
  
 Democrats sought to exploit any sign of division over the O'Donnell win. House Majority Leader Steny Hoyer said Wednesday that Tea Party candidates like O'Donnell will hurt Republicans in the fall. 
  
 "Republicans in Delaware nominated somebody that they don't believe can win -- I think, in the words of the state party chair, couldn't be elected dogcatcher," White House Press Secretary Robert Gibbs said Wednesday. 
  
 Long-distance disputes between O'Donnell and her supporters and prominent Republicans continued into Wednesday, though party leaders began to embrace her. 
  
 Former Bush administration adviser Karl Rove, a Fox News contributor, had criticized O'Donnell's candidacy Tuesday night. O'Donnell, in an interview with Fox News Wednesday morning said Rove's "credibility" had been damaged by her victory. 
  
 Asked about the tiff, Rove said Wednesday that his problems with O'Donnell concern her "character" and "background," not her ideology. 
  
 "If she wins, more power to her -- she's right on the issues," he said. "She's got to answer these troubling questions." 
  
 Former Alaska Gov. Sarah Palin, who gave O'Donnell a boost in profile by endorsing her in the final days of the campaign, said Republicans need to close ranks now that the primaries are over. 
  
 "Those who say that the GOP nominee is not elect-able or that they're not even going to try, well I say buck up," Palin told Fox News. "I have absolutely nothing against Karl Rove. ... They need to realize that the time for primary debate now is obviously over and it's time for unity." ||||| Questions Surround Del. Senate Hopeful O'Donnell

 In the latest and perhaps most surprising win for the anti-establishment Tea Party, Delaware's Christine O'Donnell beat long-term Rep. Mike Castle, a moderate, for the Republican Party’s Senate nomination. 
  
 The outcome rocked the GOP and led many to ask: Who is Christine O'Donnell? 
  
 By all accounts, she is sharp, charming and energetic. With her Sarah Palin looks — and endorsement — plus the backing of Tea Party groups, she motivated many Republicans to reject the establishment guy. 
  
 The questions come when you start delving into O'Donnell's background. 
  
 She is 41 and this is her third run for the Senate. Delaware's biggest daily newspaper, The News Journal of Wilmington, has been running stories on her problems for years. 
  
 Early in her career, she was fired from a respected Republican think tank, which she then sued for discrimination. 
  
 In 2008, her house fell into foreclosure and was scheduled for auction, until a friend and campaign worker bought it from her. She was then audited by the IRS. In an interview with NPR in August, she suggested that the audit was politically motivated. 
  
 "I ran against Joe Biden and I was audited," she said. "My mother's business was audited, and many other members of my family were audited." Asked why she thought she was audited, she said, "Who knows? It could be thug politics. It could be intimidation tactics. Either way, it didn't stop me." 
  
 At the end of the audit, she says, the IRS slapped a tax lien on the house, which had already been sold. 
  
 "See, that's the other thing ... what makes it really funny," she said. "Because it's an $11,000 tax lien on a home that I sold in 2008, so I didn’t even own the home when they put a tax lien on it." 
  
 O'Donnell calls the lien a computer error. She says it's been cleared up, but it's still on her credit report. She earns very little money now and pays half of her rent with campaign donations. She says that's justified because she's running her campaign out of her house. 
  
 And it recently came to light that her alma mater, Fairleigh Dickinson University, didn't issue her a degree in 1993 because she still owed it money. 
  
 All of this, O'Donnell says, is actually good for her: It shows that she's not a millionaire. 
  
 But O'Donnell has sent the GOP reeling like nothing in recent history. In an extraordinary bout of cyberwhiplash, e-mails from the National Republican Senatorial Committee went from asserting one day that O'Donnell was paranoid to fully endorsing her the next. 
  
 The party spent Wednesday trying to recover from Karl Rove's appearance on Fox News on election night. The Republican guru came right out and said what others had been whispering for weeks. 
  
 "And again, these serious questions about how does she make a living?" Rove said. "Why did she mislead voters about her college education? Why did it take her nearly two decades to pay her college bill so she could get her college degree?" 
  
 On Fox, Sean Hannity tried to defend O'Donnell. Rove went on: 
  
 "Did you ask her about the people who are following her home to her headquarters and how she's checked each night in the bushes? I mean there's just a lot of nutty things she's been saying that just simply don't add up." 
  
 So while Republicans are trying to look unified in their support of O'Donnell's general election bid, Rove's words are very likely ringing in their ears. "This is not a race we're going to be able to win," he said. |||||
A: 
Sarah Palin warned Karl Rove yesterday to "buck up" and get with the Tea Party program after he lashed Delaware Senate primary winner Christine O'Donnell and her "nutty" ideas. "To those who say that the GOP nominee is not electable and that they're not even going to try, well I say, 'Buck up, buck up," Palin told Fox News. Karl Rove needs to "realize that the time for primary debate is over and it's time for unity—we need to go forth and conquer for the American people," she added. Rove has been one of the most outspoken conservative critics of O'Donnell. He has already written off the Delaware Senate seat, expecting it will be lost to the Democrats. Rove has said he has no problem with O'Donnell's issues, but is concerned about her "character" and background, pointing out "troubling questions" about O'Donnell's tax dodging, fudges on her college record and her paranoia that people are following her. "How does she make a living?" Rove asked on Fox. "Why did she mislead voters about her college education?" What about "the people who are following her and how she checks each night in the bushes? There's a lot of nutty things she's been saying," he added. O'Donnell said yesterday Rove's "credibility" has been hurt by her victory. (More Sarah Palin headlines here.)
