The best anti-Trump ad is Trump when he launches against Ben Carson basically calling him incurably sick for which there is no cure, calling Ted Cruz the worst of everything when he had only praise for Cruz until it became clear he might win Iowa then Trump launched his know-nothing birther attack citing Larry Tribe a long time Democrat hack and I could go on and on endlessly but won’t.
The worst was when he said Iowa was stolen and there should be a do-over.
When DT melts down, rivals don’t need anti-Trump ads. Just play him and that’s that.
Ditto for flip-flopping untrusTED/TED two step
The debate flip-flop was one of his best, yet. He was against waterboarding, before he awkwardly paused (whose thoughts was he gathering? lol) and was suddenly for a McCain version of waterbaording.

His legal status for illegals/immigration reform flip-flop, that Brett Baier swatted him around with, was another classic .... out of the shadows aka amnesty...
