Absolutely, disgusting, classless and pathetic video.
and yet you felt compelled to post it.
Actually, I did not hear her saying voting was like having sex, so it was not a simile. In fact, I didn't hear the word virginity at all, so it wasn't a metaphor. At best, it was an implied metaphor.
(that said, I'd agree that in the first few seconds it sets itself up as a rubber commercial. I was waiting for Trojan Man to jump in behind her, unfurl his cape, and take her virginity.)
The only thing really disturbing about it, to me, was that it was for a particular candidate. If it had not decided to segueway into an Obama commercial, but instead simply encouraged voting, I might have thought it was cute. It's really rude, in my opinion, to tell people for whom to vote. But lots of ads and lots of people tell you how to vote every day, so it's nothing unusual.
