Trump will induce panic voting against him resulting in large turnouts as long as he is in the race. He will never get above 35%. NH was peak Trump. If he makes it to the general, the 47%ers will stamped the polls like a Walmart on a Black Friday.
It's because he's dangerous, arrogant, furious and nuts.
The MSM and establishment know this and fear Cruz more which is why they pump Trump every chance they get.
