Even if Hillary wins in Ohio and Texas, it’s highly doubtful she will be able to head off Obama’s nomination.
Why? If she picks up PA in April, that may sway enough Supers. McCain needs to wrap it up and go on the attack.
Obama's campaign says she has to win both by 10 points or it's over. Hillary!08's campaign doesn't make that comment, so it has a high truth probability. Even won't get it done.
That’s what I think. Even if Hillary wins tonight, they are going to fight this down to the end. Maybe even the convention.
