Gosh, I hate to agree with, GG, but since Clinton has a mathmatical chance of Clinton catching Obama in pledged delegates then I say let the fight continue...
If, however, she wins Pa. by only 55/45 and looses North Carolina by the same margin then the math may chenge to the point where she would have to win the remaining states by 75/25 in order to catch Obama... That will be a different situation...
I think that the Clintons are not yet capable of entertaining the thought that have lost, or not won... The Pa./NC should clarify it and then it coyuld be time for the Dems to turn up the heat on the Clintons...
Until then, she needs to stop punching Obama because it is now apparent to even the most casual political observer that he has a deft counterpunch...
But there is a second reason why she should quit punching Obama and that is her (and Bill's) political futures and she is loosing political gound with her personal attacks...
