Who are celebrities voting for on Tuesday? Many have announced in online videos.
Matt Damon, for example, stars in a video where he uses a ballot to instruct folks how to vote for the left-wing Working Families Party. Damon, who turned 40 on Oct. 8, also cut a video practically begging for a birthday present: your vote for the WFP.
Sylvester Stallone seems to be of a different political mindset. He didn't bother taping a Web ad, but chose instead to make his recommendation via Twitter:
"I voted did you? Gotta get the Manchurian Candidate out of the drivers seat before were ALL soaring off a cliff into Oblivion... Be smart," he said.
That tweet led to several follow-ups as some of his 101,060 followers weighed in.
"the Manchurian Candidate was a movie about fake president who was put there by foreign enemies to destroy America. Scary concept. Rise up!" he tweeted.
Despite the tweet's reference to a "president," Stallone told The Hollywood Reporter that his tweet was "in the spirit of creating a conversation" and that "Manchurian candidate" was "a reference to all career politicians."
Clint Eastwood and Clint Howard seem to agree with Stallone.
The former recently told Katie Couric that he was "not a fan" of Obama, and the clip went viral on the Internet. The latter cut two online commercials ridiculing Obama and other Democrats.
Some celebrities pretend not to care who you vote for, just as long as you vote.
Jay Z, for example, says, "I'm not gonna preach to you," but wants his fans to "vote again 2010," just as they voted two years ago for then-candidate Barack Obama.
Then there's a group of prominent Greeks — Bob Costas, George Stephanopoulos, Nick Galifianakis and others — who implore folks to vote because "it's the Greek thing to do." Democracy has its origins in ancient Greece, after all.
Some are invoking the names and images of celebrities but it's unclear if said celebrities are involved in the project, or even aware of it.
Campus Progress, for example, implores college students to "do it for Bieber." Vote, that is, because Justin Bieber is too young to do it for himself. (His Canadian citizenship would also seem to present an obstacle to voting.)
A similar but more partisan ad from the same group asks that you vote in the name of Lady Gaga because gay marriage needs to be legal.
There's also the pro-marijuana crowd coming out in favor of California's Proposition 19, like Danny Glover, Melissa Etheridge and Zach Galifianakis.
The latter went the extra mile for his cause by smoking a joint on live TV recently. A rep for "Real Time With Bill Maher" show later admitted it was a prop.
