Carson is right.
Whether he learned something from Trump or not, changed his mind, or is the best choice for President, is another issue.
But Carson is right.
Kasich, Bush and Rubio are wrong.
Its easy to just say something out of the blue when you have been saying the exact opposite for months. I don’t believe a word of it. Carson is slipping and he’s trying to get some traction. If elected he would do nothing to close the border or build the fence. The only two that would even attempt it are Trump and Cruz.
