Pennsylvania Shmensylvania

On the eve of the Democratic primary in Pennsylvania, I wonder, is this really a decisive battle between Obama and Clinton or will the duo continue to heckle each other until the convention in June? Media outlets continue to disagree about ow important the PA primary really is but in my opinion, the winner of tomorrow's primary will not win the candidacy. If anyone has any theories or predictions it would be interesting to see how the class thinks this one will play out. Will Obama stage a come from behind victory in PA and all but lock up the nomination for his party? Will Hillary trounce Barack as the polls suggest and take some momentum going into the primaries in Indiana in North Carolina?
