Doing the math on the delegates show Obama winning:
average delegate count from CBS, NBC, and CNN
Obama 1194
Clinton 1122
Average Difference = +72 for obama
Delegates at stake March 4 = 334
Delegates needed for Clinton to TIE Obama = 203
203/334 = 60.8%
This means Clinton has to win by a 20 point margin just to TIE Obama.
Most recent TX poll has clinton ahead 10 points with 10 undecided. Don't expect all 10 of those to go to Clinton, i.e. Obama wins.
Most recent OH poll has clinton ahead 17 points with 2 undecided. 19 still ain't quite 20, i.e. Obama wins.
And whoops, forgot to count the delegate advantage Obama is going to get from Hawaii and Wisconsin, i.e. Obama wins.
