Palin is going to have to withdraw.

In 1972, Richard Nixon appeared unbeatable. When Senator George McGovern won the Democratic nomination for President, virtually all of the high-profile Democrats, including Ted Kennedy, Walter Mondale, Hubert Humphrey, Edmund Muskie[2] and Birch Bayh turned down offers to run on the ticket.
Having been declined by the "name" Senators, McGovern turned to lesser-known candidates, and Eagleton, who had opposed the Vietnam War, was selected on July 14 with only a minimal background check. Eagleton made no mention of his earlier hospitalizations. Newspapers soon revealed them. McGovern and Eagleton initially joked about the case with Eagleton saying he would undergo a psychiatric examination if other candidates (e.g., Nixon) would do the same. But the charges kept coming. Columnist Jack Anderson wrote a column falsely accusing Eagleton of being arrested for drunk driving — a charge that Anderson had to retract.
Talk about unexpected Surprises, and how History repeats itself.
