If Team Obama is convinced Mitt will be the nominee, they might jump the gun before the convention and start firing the anti-Bain artillery I'm sure they've collected; after all, they have what Kennedy used in 1994, and I'm sure there's lots more material to be added since then! And Ron Paul's people seem to be doing their best to stir things up with delegates . . .
The anti-Mormon stuff is only starting to leach out -- and the polygamy thing sort of backfired, given Obama's parentage. ;-) I'm sure they'll keep trying, though.
We just need enough of this stuff before the convention. Are the May primaries still being held?
I think the May (and even June) primaries are being held, but they seem to be purely symbolic. I feel bad for the states that are spending millions to hold them, and for the voters, who clearly realize that their votes count for nothing now.
