Here's some confirmation of the claims of Rush's victorious pro-Clinton push in Texas. This seems like a good storyline for Obama to promote: one the one hand, Democrats hate Rush. On the other hand, he did meddle (perhaps decisively) in a Democratic nominating contest. Hammering the Clinton camp for being unable to win without the Rush vote, if it's presented right, seems hardly worse than the Clinton camp's attempts to basically say that only the states they won have Democrats that count, and that those Nebraska Dems can basically get bent.
Of course, there is a danger that Obama might look like a sore loser if he goes this way, but if it sticks I think it might get him some mileage, especially if he weaves it into a bigger narrative about how conservatives like Rush are afraid of him more than Clinton and are trying to sabotage him. If I were Obama I'd pull the trigger here, but quickly.
