Former President Bill Clinton told CNN Thursday his wife, New York Sen. Hillary Clinton, will have no qualms about returning to the Senate if she loses her bid for the Democratic presidential nomination.

"You know she's not — some people who run for president can't wait to get out of the Senate, or out of whatever other job she's got. She loves it. She's still doing it. She's still going to her committee meetings, going to upstate New York and trying to run for president as well," Clinton told CNN's Larry King. "So, for her personally she's going to be fine regardless. I think it'd be best for the country if she were elected president, but if voters make another choice, she's a great senator, and she loves her job, and we'll have a great life."

A new national poll shows Hillary Rodham Clinton's favorable ratings sinking like a stone, and her negatives soaring - a terrifying trend for a campaign desperately trying to convince voters she's not too polarizing to be president.

The new USA Today/Gallup survey shows Clinton's favorability rating shrunken to 45 percent - down 9 points from a similar poll taken last month, and a 13-point drop from a survey taken shortly after she announced her White House bid.

More troubling for her White House hopes, her unfavorable ratings have climbed 12 points since she entered the race, and now stand at 52 percent - meaning more Americans now dislike her than like her.

"You don't see this type of straightforward pattern very often," Gallup's polling guru Frank Newport said.
