Politicians are not celebrities. Celebrities are not politicians. ...Or, are they? The fur is really starting to fly in the election. Presidential candidate John McCain has likened Barack Obama to Britney Spears and Paris Hilton. Rappers who support Obama have released tracks dissing John McCain. What happens when politics and celebrity mix? Nothing good.

In one of his political ads, McCain seems to be trying to undermine Obama as a presidential contender - calling him a star instead of the vehicle of change Obama claims to be. It isn’t odd for politicians to use celebrities to further their own cause, and it isn’t even odd for celebrities to decide to become politicians.

So maybe it’s even the norm for celebrities and politics to mix…but should they? Sometimes, celebs can do much more harm than good when they back a certain candidate.

(Warning: the following clip contains offensive language and themes)

In a recent song, Ludacris asks to be put in office by Barack Obama, nominating himself as a Vice President for the latter. He talks of painting the White House black and urges black people to get out and vote. In the song, he names George W. Bush as the worst of 43 presidents in U.S. history. Though the tune is obviously a well-meaning support speech for Obama, much of the language is offensive.

Obama’s camp has replied that the song is “outrageously offensive.” Obama rep Bill Burton said that “Ludacris is a talented individual, but he should be ashamed of these lyrics.”

Superstar Nas has also spoken out for Barack Obama against FOX News, an organization which often seems to have Republican leanings. The singer collected signatures from more than 600,000 people who share his feelings about FOX News, which he calls “a propaganda machine.” Several times, anchors at FOX News have slipped up and addressed the candidate as “Osama” instead of Obama - and though they correct themselves when the slip is made, it seems to occur with frightening regularity.

FOX News is owned by the Fox Entertainment Group and currently reaches more than 85 million American homes.
