CNN reported Carson was heading back to FL.
That information was circulated by everyone.
Carson is too honest. He should never have said anything until after the results. If he had, he may have gotten 12 or 13 percent which would have changed everything. Oh well rookie mistake on his part. Lessons learned.
And remember that there were several polls that said Cruz was the overwhelming second choice. When some of the lower tier candidates bail, I think Trump will not be happy with what happens.
