Already voted for Cruz.
Another reason Cruz is ahead. . .probably due to backlash in response to the over-the-top very nasty and vile negative character assassination attacks by Dewhurst.
Just plain awful. . .to use a crying mother who’s son committed suicide. . .and to blame Cruz for that. . .
That ad was despicable, that ad had to be an embarrassment to at least some of the outsiders who endorsed Dewhurst, such as Huckabee and Michael Reagan. I doubt those two expected Dewhurst to pull low-life stuff like that when they endorsed him.
