Said Bush knew that there were no weapons of destruction in Irag when they invaded. Accused him of lying. Also when Jeb said his brother made us safe, Trump reminded everyone the twin towers came down on his watch.
I feel like he's trying to create a narrative where he's tough and everyone else is weak. Going after Jeb who is a wounded duck at this stage is pretty much his M.O. Doesn't seem like there will be any backlash from people who would consider voting for Trump.
Actually new polls out nationally have Cruz ahead by 2 now. Said Trump fell 15%. Woe. IMO Trump is too thin skinned to be president.
I don't know if you can attribute that drop to these comments, though. I don't think Cruz can win a GE so seeing him ahead is a good thing.
