Spirit in the Sky, but only since Loser wouldn’t really be appropriate.
I think mine would be Rock & Roll by Led Zeppelin.
Robotech’s Theme Song…
Hey!, nerds vote too.
Poison: Look What the Cat Dragged In.
Hello, There by Cheap Trick.
Are you ready to rock? Are you ready to rock?
*Ich Will* by Rammstein! Let 'em know right up front I ain’t taking shit from nobody! 
“One Love/ People Get Ready” by Bob Marley and The Wailers
The Chicken Dance. Just because I could.
Yakity Sax.
Cake - “Comfort Eagle”
*We are building a religion
We are building it bigger
We are widening the corridors
And adding more lanes
We are building a religion:
A limited edition
We are now accepting callers
For these pendant key chains…*
Honestly, I’m surprised Obama didn’t snap this one up
Mine would be the *Imperial March *from Star Wars. Just to set the tone for the regime, er… administration.
Last time I started this thread, I took Hell’s Bells by AC/DC. I still say it works for closers and 3rd and 4th defensive downs so why not me?
The 1812 Overture. I’d time the firing of my artillery on the capitol to coincide with the cannons just for the irony.
“I’m Just a Girl” by No Doubt
“I Eat Kids” by Barry Louis Polisar.
I’d promise a tot in every pot!
Lancelot’s Theme (Camelot)
No reason to be modest.
Well, I thought “The Revolution Will Not Be Televised” was funny. But then, part of the humor comes from the fact that I’m an overweight, mostly bald, twenty-four year old white nerd from an upper-middle class suburbanite background. And I’m a moderate democrat*.
Alright, for a more serious answer… Is Anybody There from 1776 would be neat if it weren’t for the anti-English parts. Although it seems like something an unpopular president would pick for a reelection campaign.
Seal’s Crazy would be good for a non-traditional candidate.
I like Right Now by Van Halen, but it’s a little cheesy, and it’s probably already been done.
I love The Kids Aren’t Alright by The Offspring, but I wouldn’t use that myself.
Hmm… I don’t really know what I’d use. Probably Crazy, because as unqualified and undiplomatic as I am, I’d be a pretty bizarre candidate to pick.
*Okay, yeah, I switched over from Republican to vote for Obama in the primaries, but I’d already been thinking about switching my registration before this election started.
Not for my own candidacy, but for new a left-of-the-Democrats party: “Time Is On My Side,” by the Rolling Stones.
Molasses to Rum to Slaves from 1776. As mentioned in another thread I don’t want to be elected for anything, but this would at least get enough attention to put a great musical in the national discourse.
To continue the 1776 riff I’d run on Piddle, Twiddle and Resolve - my indictment against the NYS legislature.
Now if only I can find a way to change “Albany” into a five syllable name, or title…
