Republican Sarah Palin and Democrat Joe Biden share the same stage in a vice presidential debate on Thursday, but the spotlight will be on the untested Palin as she tries to ease doubts about whether she is up to the job. The lone match-up of the vice presidential contenders before the November 4 election promises more than the usual drama, most of it supplied by Palin's debut in an unscripted format.
The encounter could draw a larger television audience than the 52 million who watched last week's first debate between the presidential candidates, Republican John McCain and Democrat Barack Obama. McCain's surprise choice in August of the relatively unknown Palin as his No. 2 rallied conservative support for the Republican ticket and turned the moose hunting Alaska governor into a political celebrity. But her lack of national experience and her hesitant performance in rare media interviews raised doubts about her readiness and prompted criticism even from some prominent conservatives.
She hopes a solid debate performance can halt Obama's momentum and erase concerns about her ability to step into the top job if needed. McCain, 72, would be the oldest president to begin a first term. In a Washington Post/ABC News poll released on Thursday, 60% of the voters surveyed said Palin did not have the experience to be president, up from 45% in a similar survey a month ago.
"She'll be just fine. She'll do fine tonight," McCain said on MSNBC, rejecting criticism that his campaign had mishandled her by shielding her from the media. "She's experienced. She's knowledgeable. She's very strong person. I'm proud of her record, and I'm proud of her."
Biden, 65, the chairman of the Senate Foreign Relations Committee, faces his own set of challenges as he tries to rein in his tendency to make mistakes and talk too much. He will have to tread carefully in challenging Palin without appearing condescending or aggressive. The McCain campaign launched a Web advertisement mocking Biden, noting his comments about his own high IQ, the high number of foreign workers in convenience stores and Hillary Clinton's better suitability for his vice presidential slot.
"Ready to gaffe? Yes. Ready to lead? No," the ad's narrator says.
The Biden-Palin encounter follows last week's first presidential debate between Obama and McCain. Opinion polls judged Obama the winner, and the Illinois senator has since solidified his lead in national polls and gained ground on McCain in some crucial battleground states. A flurry of new surveys showed Obama with leads in traditional battlegrounds like Florida, Pennsylvania and Ohio, and building an advantage in states like Virginia and Nevada where Democratic presidential contenders rarely do well.
Obama, who campaigned in Michigan on Thursday, has picked up steam during the Wall Street crisis over the last two weeks, with polls showing voters preferring his economic leadership. Obama and McCain, an Arizona senator, voted for the $700 billion financial bailout in the Senate on Wednesday. The television audience could be largest for a vice presidential debate, surpassing the nearly 57 million who watched in 1984 when then-Vice President George H.W. Bush, the current president's father, debated Geraldine Ferraro, the first woman vice presidential nominee for a major party.
Palin and Biden have spent several days off the campaign trail to prepare. Palin has been at McCain's Arizona retreat and Biden at home in Delaware, although he returned to Washington to vote for the bailout package on Wednesday. Both camps tried to drive up expectations for their opponent.
"I've been hearing about his Senate speeches since I was in, like, second grade," Palin, 44, told CBS News in a sly reference to their difference in age. "I'm the new energy, the new face, the new ideas, and he's got the experience."
Obama aides said they have studied her debates during her 2006 campaign for governor of Alaska.
"Anyone who has watched any of her earlier debates would agree she is a skilled debater," Obama campaign manager David Plouffe said.
