If Joe wins, if he caucuses with the GOP, it works for everyone but him.

Wouldn't the GOP will dump all the failures on him that they can if/when it comes time for PayBack2008?

Making him the SecDef would have to be radioactive, I doubt it would work in any party's Congress. Why would the GOP want to look like it is surrendering its War on Terror to the CFL party?

Don't the Democrats gain credibility, saying 'Look: he made some very bad decisions and would not change. He took his bad judgement with him across the aisle, where it was most welcome. Vote Democratic in 2008. Thank you."

Maybe Joe will see this coming and bail.

Can anyone say with any certainty that he's do the right thing with the party who nurtured him for decades? He's played the eager fool every time the GOP asks him to. He threw away his party's primary rather than stand on his hind legs and really run. He merely moped around waiting to be crowned and have the party do some hatchet work.

With every threat he makes, the Democrats look more like punching bags.

So what's the harm?
