Congressman Massa's resignation - why?

[Sean]

So has everyone been seeing the stories about New York Democratic Congressman Eric Massa resigning to deal with the possible recurrence of his cancer - wait, I mean because of an ethics probe - wait, I mean because the Democratic leadership is forcing him out over his opposition to healthcare reform?

My best guess is that the guy resigned over legitimate health concerns, since that's what he initially cited as the reason, and since he says he didn't learn of any ethics probes until after he had announced his resignation. But when he learned of the ethics probe - the contents of which he admitted to being guilty of until it became sexual in nature - then suddenly he claimed he hadn't resigned over his health, he resigned because the conspiratorial Democratic leadership forced him out!

The evolution of his story just strikes me as disingenuous at best.
