Oh please. Read my post again, and don't try to spin this as some sort of free speech issue. Nobody is trying to have the government take this off the air, and nobody is trying to impugn the entire left.
Obama should repudiate this ad. It's very easy to run a campaign based on a "new style of politics" when you have 527s running all your attack ads for you.
He should have. Is Obama taking cues from George Bush now?
You certainly are by the style of your writing.
Once again, Obama has nothing to do with this ad. He's not involved with it, once again. If he wants to denounce it, he can go ahead. If Obama says he's running his campaign based on a "new style of politics," why should he tell detractors of McCain what to say? It's not part of his campaign, it's part of a group's campaign to stop John McCain. Obama has run plenty of attack ads himself, just like all politicians do. To repeat myself, this ad has nothing to do with Barack Obama and shouldn't be painted as such, although you're trying extremely hard to do so.
Obama is taking cues from politicians, just as politicians should.
