The battle for the senate is over. The comments didn’t hurt him at all. Bredesen and O’Rourke are slipping away and Hyde-Smith will easily make it to the runoff.
Not to nitpick, but is Texas truly slipping away? The most recent polls, even excluding that Junkie Reuters one, shows him catching up or even tide slash slightly ahead of Cruz. It would still be an upset for him to win oh, sure, but I'm not aware of any recent developments indicating the momentum has shifted back to Cruz.
Bredesen was down 5 in that recent Fox poll, which is probably enough to say the momentum has shifted away from him, just as everyone here is predicted would like eventually happen.
