Two weeks ago, the ire of Trump supporters was most likely to be aimed at Florida Senator Marco Rubio, who is no longer in the race.

Republican voters who do not support Trump haven’t liked him for a while. This week, two in three Cruz and Kasich voters have a negative opinion of Trump. This is not much different from their opinions two weeks ago.

Only about one in four Trump supporters claim they would be “upset” if Cruz or Kasich won the nomination. But 41% of those not supporting Trump would be “upset” at a Trump nomination victory.

But – if Trump became the GOP nominee — would those current opponents stay home? Or even defect on Election Day?
