Obama's 3 (4 if you count Guam) were big but...

That's not where the real fight is. At the moment, Obama is positioned to win most of Maine, Virginia, DC, Maryland, Hawaii, and Wisconsin as well heading into Junior Tuesday. Obama needs to win these states for the momentum needed to win states with troublesome demographics for him on March 4. This could be the day the nomination is decided if Obama is somehow able to swing Ohio and/or Texas which are troublesome places given the high percentage of Latinos in Texas and the high working class white population in Ohio. If Obama only wins Vermont or Rhode Island on March 4, it's back to square one yet again. If Obama sweeps on March 4, though it's off to the races heading into friendlier states like Wyoming and Mississippi before Pennsylvania on April 22. One thing to keep in mind regardless of how things play between now and April 22 is that after Pennsylvania, the remaining states become very friendly to Obama with Indiana, North Carolina, Kentucky, Oregon, Montana, and South Dakota all holding contests before Puerto Rico has the last primary on June 7. To sum up. Obama needs to sweep until March 4, steal Ohio or Texas, and then try to win PA. If he does that, he'll be the nominee based on the other states involved. Clinton needs to try to win a state before March 4 and then lock down Obama in the big states of Texas, Ohio, and Pennsylvania. If something in between those two possibilities takes place, we're headed for a floor fight in Denver.
