Your free to believe Hillary is stronger than Obama against McCain. But if she gets this nomination she will have done it via the superdelegates. There is going to be alot of angry black voters out there that think she stole the nomination from Obama and they could stay home.
One more thing, you seem to be forgetting one of the reasons for Operation Chaos is to prolong the democratic primary so they bloody each other up since McCain isn’t willing to do so.
Some blacks will stay home, but if Hillary wins PA and IN, and only loses NC because of a huge turnout of black voters for BO, she will have a very good case to make to the superdelegates, including those pledged to BO, that the exit poll demographics show that BO is fatally weak in the states Dems must carry to win. If black superdelegates and others explain this right, Hillary won’t be seen as stealing the nomination.
That’s why I think Obama, not Hillary, is the one Rush ought to help next. Obama can point to his white support in the late primaries, but it will be ephemeral, since it will include white Chaos Reps for McCain... or at least resigned to voting for McCain.
