Among Trump supporters, Carson is the top second choice, far ahead of any other candidate.

Seven in ten Republican primary voters would support Trump if he became the party’s eventual nominee, though many would have reservations. Twenty-nine percent would support Trump enthusiastically, while 42 percent would support him with reservations, and another eight percent would only support him because he is the party’s nominee. One in five Republican primary voters would not support Trump if he became the nominee.

Trump continues to be viewed as the most electable candidate in a general election. Thirty-five percent say Trump has the best chance of winning in November 2016, followed by Ben Carson (18 percent).
