Sen. John McCain

Stephen Baldwin

Unlike his left-leaning brother Alec, Stephen has been a strong supporter of the Republican ticket this year, appearing in television ads for GOP senate candidates. On NBC’s “Today Show,” Baldwin said, “I don’t believe personally that Barack Obama cares for America as authentically as John McCain.” Last month, Governor Sarah Palin referred to Stephen as her “favorite Baldwin brother.”

Sylvester Stallone

If the guy that played Rocky and Rambo can’t sway voters, then there’s something fundamentally wrong with this country. Stallone voiced his support for McCain in January.

“There’s something about matching the character with the script,” Stallone said on a Fox News morning program. “And right now, the script that’s being written and reality is pretty brutal and pretty hard-edged, like a rough action film, and you need somebody who’s been in that to deal with it.”

After hearing the endorsement, Sen. McCain said, “I’m going to Philadelphia and running up the steps.”

Wilford Brimley

I don’t know why the McCain campaign hasn’t capitalized more on Brimley’s endorsement. “Mustaches for McCain.” “The mustache and the maverick.” The possibilities for catchy campaign slogans are endless. Brimley, the actor famous for his TV commercials with Quaker Oats and Liberty Mutual, threw his support behind McCain at the beginning of this year.

Sen. Barack Obama

Oprah Winfrey

Oprah’s backing of Obama was probably the most talked-about celebrity endorsement of the campaign. She’s one of the most recognizable faces in America, and her magazines and TV show reach millions of women across the country. Even in the primaries, some political pundits began to speculate about the “Oprah affect,” claiming she could have helped Obama win close to a million votes. If Obama doesn’t win, you can kiss those famous “Obama’s favorite things” episodes goodbye.

Robert De Niro

De Niro has spoken at Obama rallies and appeared on numerous cable news shows to stump for the Democratic nominee. De Niro gained attention from political analysts after what became known as his “inexperience endorsement” at an Obama rally.

“It’s clear that Barack Obama does not have the experience to just let the special interests run the government,” De Niro said. “It’s his inexperience in the arrogance that led to the destruction of America’s international stature. That’s the kind of inexperience I could get used to.”

The music industry

It seems as though nearly every band and musician that doesn’t have a video on “CMT” has thrown their support behind Obama. The Arcade Fire, Wilco, the Grateful Dead, Ludacris, The Decemberists, will.i.am — the list goes on and on. Many artists have held fundraiser concerts for the Obama campaign, while some have taken their endorsements to YouTube.
