I was thinking the same thing might happen. But, is that so bad? I believe McCain will have no problem beating Hillary in the general election, but I'm not so sure about Obama.
As others have pointed out: if Hillary loses the nomination this year, she will be back in 2012. But, if she is trounced in the general election, the Clinton political machine would be finished for good.
Usually those that don't want people to vote for Hilliary in the primaries are really trying to get Obama to win the general election next November.
ObaMessiah has quite a powerful pull.
