Just a couple of notes.
The delegates are still being counted and the numbers will probably change a bit since the Texas caucuses are still being counted, but right now the total counts for the four states are:
HRC managed to turn around the ship a bit but not nearly enough yet. Unless Obama self-destructs he is still the leader by 148 delegates with 560 left to be handed out. HRC will need to win by bigger margins if she wants to close the lead. Plus, there is no reason to believe the super delegates are going to buck the popular delegate count, not if they don't want to screw the party for years.
PA is up next and I think it may be the only one that day. That'll be crazy.
One other point, the turn out. I haven't looked at the numbers today but last night both HRC and Obama, individually, had twice as many votes as McCain. That's nuts.
