The Filibuster Scam

Democrats can't enact Buffet Rule because they don't have 60 votes? Give me a break. Is a 60-vote margin ordained in the Constitution? I don't think so. I know that if they wanted to force a filibuster, they could, so why don't they? Maybe because then all those Senatorial fat cats would have to raise their own taxes? Could it be? Otherwise, why not make the Republican filibuster the raising of tax rates on the rich--wouldn't it be good to make them do it--for the election, I mean? Something smells rotten here and I think it's the Democratic leadership.
