When crossover voters were asked how sure they were, 63% of the Democrats who said they would crossover were "100% sure."

Mercury Analytics dial-tested Trump's first campaign ad, which touches on a variety of issues including ISIS, radical Islamic terrorism and illegal immigration. The firm found 25% of Democrats "agree completely" that the ad raised some good points;  while 44% of Democrats agree "completely" or "somewhat."

The image below is of the last screen of the dial-testing scores, which shows the ad rated the best among Democrat defectors. The video, which is not embedable, can be seen here.
