With some of the comments being made on this thread, I am not sure how many watched the debate. Cruz said that Rubio spoke Spanish on (I think it was on Univision ) and said Rubio told them he would not recind Obama's immigration policy. Rubio responded how would he, Cruz know what he said because he accused Cruz of not being able to speak Spanish. Cruz then replied back to Rubio in Spanish. It was a great comeback.
The dumbest part of it all has to be Rubio thinking that no one at all can speak Spanish and that no copy of his Univision appearance exists. Either he thinks that or he just played the lamest bluff ever.
