At times last night Trump appeared near tears.
When Rubio took the gloves off, Trump looked like he was having seizures.
His eyes were blinking, his face was beet red and he was breathing like he was oxygen starved.
Rubio said at one point , he may build a a wall, but if he does you can be sure that that he will use undocumented labor."
Trump is a bully, stand up to him and he wilts.
