and very probably lean toward Clinton.

This year it's got a much smaller pool of states, half the size it was in '08, about 1/3 are states that Sanders can win.

The critical thing in the states he loses will be the size of the margin and the resulting delegate distributions. She'll do well, but I don't think it's looking like he'll be reduced to being non-competitive then

The delegate assignment could get very difficult for Sanders on Mar 15th. He really needs to close up in Illinois and Ohio to balance what looks like a loss in Florida which iirc is a winner take all contest.
