Also interesting to note that they were asked about the Sarah Palin endorsement. 14% of people said that it made them more likely to vote for Trump, 24% said it made them less likely (60% no effect, 2% unsure). I bet it's still positive, as most of the people who said it made them less likely to vote for him probably already were not going to anyway.
Figured I'd also include this, but as a separate post:
