Screw It

Obama should run an ad saying that McCain wants to raise your taxes.
(Based on the the truth known by economists, including Larry Summers, who just said this on TV, that a deficit is really a tax increase on future generations.)

And then he should run an ad about how McCain got a $2 billion earmark to give Arizona an all-nude, pederast-staffed waterpark with a signature water slide called The Sodomizer. Because fuck it, you gotta fight fire with fire.

Update:
Others agree with me.
