They are just Cruz supporters infiltrating Trump Rallies
The establishment would much rather run against Cruz than Trump. HilLIARy (or Sanders) MIGHT BEAT Cruz- maybe not, but its a lot closer than Trump - whou would generate a landslide. Look at the crowds!
And with the typical voter fraud they could pull off a dem win against Cruz. They were able to generate 10% to defeat Romney (he was up by 10 before election day)
That’s not what the head-to-head polls say. Quite the opposite.
