Ludacris Blows Chance of Being Secretary of State

There are a lot of people all kinds of upset over the new Ludacris song called "Obama is Here."
The Obama campaign calls it "outrageously offensive." In the song Ludacris calls President Bush mentally handicapped and says John McCain doesn't belong in "any chair unless he's paralyzed."

The part about the chair I don't totally get. I guess the chair is the presidency? Nonetheless, I'm fairly certain it's not a nice thing to say about John McCain.

I've listened to the song. The only place I found the full lyrics was on hiphopmusic.com. I copied them from there:

I'm back on it like I just signed my record deal
Yeah the best is here, the Bentley Coup paint is dripping wet, it got sex appeal
Never should have hated, You never should've doubted him
With a slot in the president's iPod Obama shouted 'em
Said I handle my biz and I'm one of his favorite rappers
Well give Luda a special pardon if I'm ever in the slammer
Better yet put me in office, make me your vice president
Hillary hated on you, so that b*tch is irrelevant
Jesse talking slick and apologizing for what?
If you said it then you meant it how you want it head or gut?
And all you other politicians trying to hate on my man,watch us win majority vote in every state on my man
You can't stop what's bout to happen, we bout to make history
The first black president is destined and it's meant to be
The threats ain't fazing us, the nooses or the jokes
So get off your a**, black people, it's time to get out and vote!
Paint the White House black and I'm sure that's got 'em terrified
McCain don't belong in any chair unless he's paralyzed
Yeah I said it cause Bush is mentally handicapped
Ball up all of his speeches and just throw 'em like candy wrap'cause what you talking I hear nothing even relevantand you the worst of all 43 presidents
Get out and vote or the end'll be near
The world is ready for change because Obama is here'cause Obama is here
The world is ready for change because Obama is here, yeahcuz Obama is here
