Sarah Palin's candidacy for Vice President of the United States was publicly announced by then-presumptive Republican Party presidential candidate John McCain on August 29, 2008. As part of the McCain presidential campaign, Palin, then the incumbent Governor of Alaska, was officially nominated by acclamation at the 2008 Republican National Convention on September 3. The McCain–Palin ticket lost the 2008 presidential election on November 4 to the Barack Obama–Joe Biden ticket.

Selection

Senator John McCain began a search for a running mate to join the Republican ticket after clinching the Republican nomination. Former candidates Mitt Romney and Mike Huckabee were mentioned as possibilities, as were many other leaders in the Republican Party and the business world. Over Memorial Day weekend, McCain invited Romney, Florida Governor Charlie Crist, and Louisiana Governor Bobby Jindal to his Sedona, Arizona ranch for informal get-togethers intended to assess personal chemistry for possible running mate selection.

McCain then announced plans to reveal his running mate the day following the conclusion of the Democratic National Convention, and just a few days before the start of the Republican National Convention. During the running mate deliberations, McCain had favored Joe Lieberman, who shared his romantic sense of righteousness and honor.Thomas, "A Long Time Coming", pp. 120–122. But the opposition from social conservatives, who objected to Lieberman's pro-choice views, was too strong, and a Lieberman pick might have caused a floor fight at the upcoming convention. McCain wanted someone who would shake up the race and reinforce his image as a maverick, so he decided against more conventional choices on his short list including Romney and Governor Tim Pawlenty.

McCain had only talked to Palin a few times, and the campaign's vetting operation had mostly relied on Internet searches to check her background.Thomas, "A Long Time Coming", pp. 122–125. Steve Schmidt and Nicolle Wallace assumed, incorrectly, that Palin would have a basic working knowledge about the public policy debates of the previous five to ten years.Couric, Katie, host. "The Palin Interviews, 10 Years Later: Part One." Katie Couric, Katie Couric podcast, 27 Sept. 2018. Palin's career in Alaska had shown maverick tendencies similar to McCain's, and McCain hoped that Palin's youth, reformist record, appeal to social conservatives, and appeal to disaffected female Hillary Clinton voters would outweigh her lack of national and international visibility and experience.

According to the book Game Change, on the weekend before John McCain made his vice-presidential pick, McCain's advisor Arthur Culvahouse asked attorney Ted Frank to prepare a written vetting report on Sarah Palin:Heilemann and Halperin, Game Change, p. 362.

Announcement On August 29, the day after the Democratic Convention, John McCain introduced Sarah Palin in a speech at Wright State University in Fairborn, Ohio, a suburb of Dayton."McCain taps Alaska Gov. Palin as vice president pick" , CNN August 29, 2008. Retrieved August 29, 2008. Palin announced, "Hillary left 18 million cracks in the highest, hardest glass ceiling in America. But it turns out the women of America aren't finished yet, and we can shatter that glass ceiling once and for all". One of McCain's aides privately remarked via an American football metaphor during the announcement: "We just threw long."

Initial reaction After announcing Palin as the presumptive vice-presidential nominee, the McCain campaign received US$7 million in contributions in a single day. According to a survey by The Washington Post/ABC News published on September 9, 2008, John McCain had gained huge support among white women voters since the announcement; he had not only surpassed the Democratic Party candidate Senator Barack Obama in white women voters, but also amassed a lead of five percentage points in the Gallup polls. John Zogby found that the effects of Palin's selection were helping the McCain ticket since "She has high favorability numbers, and has unified the Republican Party."

The choice received generally positive reactions from Republicans and conservatives. Victor Davis Hanson stated "the timing and choice were inspired", and Mark Steyn stated he was "happy" over the choice. Connecticut Governor M. Jodi Rell said of Palin, "She is strong. She is capable. She is articulate," and suggested opponents should not underestimate her. Independent-Democratic Senator Joe Lieberman stated that McCain made a "bold choice" in picking a "maverick who has done exactly the same thing at the state level that he's done at the federal level". However, some Republicans did not receive the choice favorably. Charles Krauthammer of The Washington Post wrote, "The Palin selection completely undercuts the argument about Obama's inexperience and readiness to lead. ... To gratuitously undercut the remarkably successful 'Is he ready to lead' line of attack seems near suicidal." David Frum of National Review wrote: "The longer I think about it, the less well this selection sits with me. ... If it were your decision, and you were putting your country first, would you put an untested small-town mayor a heartbeat away from the presidency?". Following an NBC interview, Peggy Noonan commented, "It's over ... the most qualified? No."Noonan, Murphy trash Palin on hot mike: 'It's over', by Ben Smith, September 3, 2008.

Republicans in Palin's home state, Alaska, had mixed reactions to the news. Alaskan Attorney General Talis Colberg, a Palin appointee, remarked that, "It's wonderful. It was an emotional thing to see the governor walk out with her family and I say, wow, I work for her." Alaskan State Senate President Lyda Green, a Republican who had repeatedly sparred with Palin after she became governor, remarked, "She's not prepared to be governor. How can she be prepared to be vice president or president?" Larry Persily, a Palin staffer, and Jim Whitaker, the Republican mayor of Fairbanks, indicated their support of Palin as governor, but questioned whether she was ready to serve as vice president. Other Alaskan politicians, such as Republican Gail Phillips, expressed surprise.

Kari Sleight, publisher of the Mat-Su Valley Frontiersman, which covered much of Palin's life in Wasilla, endorsed Palin for vice-president. "While some question Palin's experience, they cannot question her leadership. A person is either a good leader or not, and Palin has exhibited great leadership skills in all positions she's held. There is an argument to be made that leadership, and the qualities that define a good leader, are inherently more important than experience."

Palin's positions and policies became the focus of "intense media attention" and "scrutiny" following her selection. Expectations from her speech at the Republican National Convention was heavily covered by the media. Some Republicans argued that Palin was subjected to unreasonable media coverage, and a Rasmussen survey showed that slightly more than half of Americans believed that the press was "trying to hurt" Palin with negative coverage, a sentiment referenced by Palin in her acceptance speech. A poll taken just after the speech found that Palin was then slightly more popular than either Obama or McCain with a 58% favorability rating. Palin was also a draw with Catholic voters; the poll found that 54% favor Palin and 42% find her unfavorable, a 12% difference, while Joe Biden was viewed favorable by 49% to 47% unfavorable.

Palin also became a "ubiquitous presence on newsstands," appearing on the cover of both Newsweek and Time, among others. The appearance on the cover of Time was particularly notable as Jay Carney, the newsmagazine's Washington bureau chief, has been vocally critical on what he has said is a lack of media access to Palin, concerns which were dismissed by the McCain campaign.

Former New York City mayor Rudy Giuliani said that Palin was more qualified to be president than Democratic presidential nominee Obama, citing Palin's executive experience, saying of her, "She's vetoed legislation, she's taken on corruption, and in her party, and won. She took on the oil companies and won. She administered a budget successfully," and of Obama, "He's never run a city, he's never run a state, he's never run a business, he's never administered a payroll, he's never led people in crisis". He also stated, if Sarah Palin had been president when the U.S. came under attack on September 11, 2001, he's confident she would have been able to handle the crisis.

According to The Washington Times, Palin's faith has made her a "favorite with the staunchly pro-Israel neoconservative elements in the Republican Party". Palin displays an Israeli flag in her governor's office in Juneau. Palin has received a strong endorsement from the Republican Jewish Coalition,Evangelical faith drives Palin's pro-Israel view, by Ralph Z. Hallow. Published in The Washington Times on September 4, 2008. Retrieved September 8, 2008. and has been described as a "direct affront to all Jewish Americans" by Democratic Congressman Robert Wexler of Florida, and as being "totally out of step with Jewish public opinion" by the National Jewish Democratic Council.

Senator Obama commented on Palin in an interview with 60 Minutes:

Convention

Palin accepted the vice presidential nomination of the Republican party at the convention on September 3.

Senator John McCain had asked Bush speechwriter Matthew Scully to write the acceptance speech for his vice presidential nominee, whom McCain had not yet chosen. Scully wrote the speech two weeks before the convention. He wrote the speech for a man to deliver, not a woman. Four days before the convention, Scully was surprised when he was informed that Alaska Governor Sarah Palin was to be McCain's running mate. Scully then worked all night to tailor the speech to Palin and also to incorporate new campaign strategy shifts that were being rapidly formed in intensive discussions by McCain campaign staff.

Palin delivered the 40-minute speech at the convention on September 3, 2008.

Election issues

"Bridge to Nowhere"

On August 29, when first introduced as McCain's running mate, Governor Palin told the crowd: "I told Congress, thanks but no thanks on that bridge to nowhere" – a line that garnered big applause. Early McCain–Palin television advertisements claimed that Palin "stopped the Bridge to Nowhere".

These claims have been widely questioned or described as misleading in several newspapers across the political spectrum. Howard Kurtz called this a "whopper", writing: "She endorsed the remote project while running for governor in 2006, claimed to be an opponent only after Congress killed its funding the next year and has used the $223 million provided for it for other state ventures." Newsweek, commenting on Palin's "astonishing pivot", remarked: "Now she talks as if she always opposed the funding."

McCain also weighed in on the Gravina Island Bridge. In advertisements, McCain labeled the bridge as wasteful spending, and in an August 2007 town hall speech recorded on video and quoted again on April 30, 2008, he blamed the Minneapolis I-35 bridge collapse on the Gravina Island Bridge. His advertising and comments that (before September 21, 2006) contradicted Governor Sarah Palin's support of the bridge drew the attention of the media when he chose Palin as his running mate, opening the ticket to charges of hypocrisy.
