The Democratic Senatorial Campaign Committee has some very clever folks working for them. Their latest ad is a very well done spoof of the PC vs. Mac ad.
Instead of "I’m a PC and I’m a Mac," it’s now "I’m a Democrat and I’m a Republican." And instead of "I have that virus going around v. Macs have no viruses," it’s "I come up with ideas in the U.S. Senate to help Americas v. I block them." [Party of No]
