* = The 14 Iowa delegates for Edwards might switch at the March 15 county caucuses. ** I did not include the new online poll showing Obama up 14 in Texas, which I think is utterly bougs.
Would winning Ohio and Rhode Island be enough for Clinton to continue on to Pennsylvania? It isn't clear. Obama will clean up in Vermont, Wyoming and Mississippi, and also probably win the delegate count in Texas. Overall, this means it is unlikely that Clinton will make up any ground at all in the pledged delegate count between now and March 15th.
Still, I think that Clinton will continue forward to Pennsylvania as long as she wins Ohio. With superdelegates, Florida, and Michigan included, she still leads the overall delegate count by 31. (Actually, only 23 if you use my delegate count. Even then, that is only because she leads Michigan 80-1.) As long as she leads in some sort of delegate count, and can win Ohio on March 4th, I just don't see her dropping out after the extensive arguments her campaign has made on those subjects. Obama's path to the nomination right now seems to be either to win both Ohio and Texas, or to win Pennsylvania and take the lead according to all delegate counts.
