Hollywood has been generously giving to candidates making a 2008 run for the White House - and some of those contributions are coming from your favorite TV stars. The Biz recently took the data filed with the Federal Election Commission to find out where they stand before the presidential primary season begins.

Senator Barack Obama has been neck and neck with Democratic nomination rival Senator Hillary Clinton in showbiz fundraising, but he's got a longer list of TV actors who've opened their checkbooks for his bid. The list includes Ellen Pompeo ( Grey's Anatomy), Zack Braff ( Scrubs), Melina Kanakaredes ( CSI: NY), Adrian Pasdar ( Heroes), Adam Arkin ( Life), Rob Morrow ( Numbers), Dennis Haysbert ( The Unit), Isaiah Washington ( Bionic Woman), Tate Donovan ( Damages), Seth MacFarlane ( Family Guy) and Will Forte ( Saturday Night Live). Chris Rock, Tyra Banks and Oprah Winfrey are also in the Obama camp along with writer-producers J.J. Abrams, Amy Sherman-Palladino, Steven Bochco, Chuck Lorre, Greg Daniels and Tyler Perry. On the executive side, the givers include Fox Entertainment president Kevin Reilly, Warner Bros. Television President Peter Roth and CBS Paramount Network Television Entertainment Group president Nancy Tellem.

Clinton is apparently a hit with the daytime-talk-show crowd - her contributors include Martha Stewart, Jerry Springer and Star Jones. Donations have also come from Joely Fisher ( 'Til Death), Khandi Alexander ( CSI: Miami), Maura Tierney ( ER), Jon Tenney ( The Closer), Sharon Lawrence, Bradley Cooper ( Nip/Tuck), Marg Helgenberger ( CSI), NBC Entertainment chairman Ben Silverman, Brothers & Sisters writer-producer Greg Berlanti and News Corp. president Peter Chernin.

Senator John Edwards' financial supporters include Larry David ( Curb Your Enthusiasm), Jean Smart ( Samantha Who?), Monk's Tony Shalhoub, Desperate Housewives hunk James Denton, CSI's Robert David Hall, Hank Azaria, Jason Alexander and Cold Case creator Meredith Stiehm.

Representative Dennis Kucinich has raked in bucks from Esai Morales ( Jericho), Shelley Morrison ( Will & Grace), Casey Kasem and Days of our Lives diva Deirdre Hall.

Senator Chris Dodd's contributors list includes NBC Sports chairman Dick Ebersol, Saturday Night Live executive producer Lorne Michaels, ABC Entertainment president Stephen McPherson and Chernin.

New Mexico governor Bill Richardson's only TV luminary is Cane's Jimmy Smits, who also shelled out for Clinton and Obama, while Senator Joe Biden can claim Bradley Whitford.

Showbiz contributions shrink considerably when you get to the Republican side. Fred Thompson got help from his former boss Law & Order creator Dick Wolf and Wheel of Fortune host Pat Sajak. Rudy Giuliani's list of contributors includes Kelsey Grammer, Orson Bean and 24 executive producer Joel Surnow. Surnow's support of the former New York mayor might come as a disappointment to Senator John McCain, a huge 24 fan (he even had a cameo one season). But McCain has received checks from SNL's Michaels and producer Jerry Bruckheimer.
