Hillary Clinton: Sarah Palin Exciting but Not Vote Worthy

Sen. Hillary Clinton, who came close to making history as the first female presidential nominee, concedes that Gov. Sarah Palin has created a lot of excitement as a possible history-making first female vice president.

Palin's presence on the Republican ticket has drawn Sen. John McCain into a dead heat with the Democratic ticket of Sens. Barack Obama and Joe Biden, fueled largely by a surge in support among white women.

"A lot of people are missing the boat here," Clinton told ABC News' Diane Sawyer, aboard the "Good Morning America" Whistle-Stop Express.

Palin has generated a great deal of interest, Clinton acknowledged, but added, "That's not a good enough reason to vote for that ticket. There's a lot of talk in the country about who are you for in this election, but that's not the right question. The right question is, who is for you."

Clinton suggested that the McCain-Palin team doesn't understand "the struggles you face."

"So I don't think it's inconsistent for a lot of people to say well hey, that's exciting, what an exciting pick, and still say, but that's not the ticket for me and my family," she said.

The New York senator also dismissed any suggestion that Biden hasn't been a strong running mate for Obama, particularly since Palin suggested Obama may be regretting not selecting Clinton, and Biden himself recently said that Clinton might have been a better choice.

Clinton said she has full confidence in Biden, praising his knowledge of the economy and world affairs.

"We have a great Democratic vice presidential candidate," Clinton told "GMA."

"Joe Biden is a friend of mine. He's been a strong leader both on issues here at home when it comes to the economy and the stresses on middle class working families, and he understands the strategic challenges that we face around the world. So I'm very happy going out campaigning as hard as I can for both Barack and Joe."

Palin will rejoin McCain on the stump today in Ohio, but her candidacy also hit some bumps on the campaign trail.

The National Organization for Women will snub Palin's history-making candidacy and endorse the Obama-Biden ticket Tuesday in Washington. Palin's opposition to abortion rights is a major stumbling block for Now and other women's rights organizations.

Palin is also at odds with an Alaskan commission that is looking into her dismissal of a former public safety commissioner.

Her campaign announced today that she will not speak with the commissioner assigned to investigate whether the dismissal was proper, saying the probe has been "tainted" by politics.
