Look, the fluffers in the media are comfy with the notion that John McCain is beyond reproach. Democrats have to stop agreeing with them or it will come back and bite us in the ass.
McCain wants to pretend he's as pure as the driven snow, fine. We need to start reminding people that he was implicated in a real bipartisan scandal back in the 1980s. He was one of the Keating 5. Now, the press has bought his explanation that it was an "oversight" on his part, but how exactly is leaning on a federal regulator to stop investigating a key contributor an "oversight." It sounds like a sin of commission with malice aforethought to me.
Fast forward to now and McCain wants to palm off fig leaf "reform" which will essentially give a bunch of crooks a mulligan. Obama is too smart for that; McCain is worried someone with a little star power will rain on his parade so he throws one of his premeditated tantrums. We can't take that flavor of disingenuousness sitting down.
The Repubs appoint a guy who passed out tobacco money on the House floor to head their reform efforts in the House, and in the Senate they have a guy who played a willing patsie in an influence peddling scandal. That's today's Republican Party for you.
