The Hollywood Primary: the Oscars of fundraising

WASHINGTON (CNN) - What do Hugh Hefner, Jennifer Aniston, Jerry Springer, and Mr. Spock have in common? They've all weighed in on the 2008 presidential race and given their two cents (plus a little extra) to their favorite White House hopefuls.

Scores of Oscar-winners, sit-com actors, and high-powered studio executives have opened their wallets this year and given much needed campaign cash to several appreciate candidates, according to a CNN review of reports filed with the Federal Election Commission over the weekend.

Some stars are regular political contributors, like actress Susan Sarandon and Barbra Streisand, but several, like Aniston and "Scrubs" actor Zach Braff, are fairly new to the game.

A few donors, like Streisand and film director Steven Spielberg, couldn't decide on a single candidate and gave to all three Democratic frontrunners: Hillary Clinton, Barack Obama, and John Edwards.

While Democratic candidates have fared best so far among these high-profile donors, Republican Rudy Giuliani scored a handful of notable contributions, including checks from comedic actors Adam Sandler and Kelsey Grammer.

Here is a list of more celebrities who contributed to the 2008 presidential candidates from January through March 2007.
