I almost expect McCain to go third party.
I wouldn't be surprised. He knows that age and health wise, this is his last chance. And it's all about McCain.
What an unlucky irony if Hillary were to get in office the same way that Bill did--because a third party candidate split the vote.
Which, very likely, is Hillary's plan.
It's possible, though, that in a three-way race, McEgo might steal more Democrat votes than Republican ones.
