Biden, Palin Enter Election Day Fray in New Jersey, New York and Virginia

WATERTOWN, N.Y., Nov. 3, 2009— -- Political A-listers are hitting the campaign trail today to fire up crowds as Democratic and Republican candidates run neck and neck in three hotly contested elections.

And at the front of a full-scale sparring match leading up to today's voting: Vice President Joe Biden and his former opponent, Sarah Palin.

The former Alaska governor is supporting conservative candidate Douglas Hoffman, running for the congressional seat representing New York's conservative, upstate 23rd District. The endorsement somehow made Biden think of oil.

"The fact of the matter is that Sarah Palin thinks the answer to energy was drill baby drill," Biden said Monday at a fundraiser here for Hoffman's Democratic opponent, Bill Owens, referring to Palin's own campaign slogan last year. "No, it's a lot more complicated, Sarah, than drill baby drill."

The former vice presidential candidate did not sit back quietly, responding to Biden on her Facebook page.

"There's one way to tell Vice President Biden that we're tired of folks in Washington distorting our message and hampering our nation's progress: Hoffman, baby, Hoffman!" she wrote.

For Palin, the endorsement comes as she tries to position herself politically, while, some experts say, a win for Hoffman today could signal that she's bringing back elections for the GOP.

"Sarah Palin is gaining a lot from this because she is maintaining a sense that there is still a political race going on between Sarah Palin and Joe Biden," said David Gergen, former presidential adviser and a professor of public service at Harvard University. "And, by the way, she has a big book coming out. I think Sarah Palin gives one of the faces to this movement we've seen, the tea party folks and the town hall folks and this sort of populist resentment that is bubbling up in one place after another."
