Sarah Palin on Thursday will be in Kentucky to help raise money for Republican Senate candidate Rand Paul.

Palin was already set to be in Louisville for a speech at the National Quartet Convention but added the lunchtime fundraiser, according to the Paul camp. Details have yet to be released.

Palin endorsed the Tea Party-backed Paul in May and has donated to his campaign, according to the Lexington Herald-Leader.

Meanwhile, Democrats are citing Paul in their own fundraising plea.

Sen. Charles Schumer (D-N.Y.) identified Paul and Nevada Republican Sharron Angle as "real threats to everything we've come to count on in this country, from Social Security to civil rights."

Soliciting contributions to the Democratic Senatorial Campaign Committee, Schumer wrote in an e-mail to supporters, "We've got to hit our goal of raising $290,524 by midnight Saturday so we don't have to cede an inch to those from the hard right who want to destroy all that we've worked so hard to accomplish — like expanding health care and reforming Wall Street.

"This moment is so critical because this is when we figure out how much we can devote to each race."
