I certainly don’t think he meant to, but Cruz allowed himself to get derailed into a five-day-long mud-wrestling contest with Rubio, which will benefit neither.
Since Cruz’ numbers are going up and Rubio’s are going down, it seems like the mistake was Rubio’s.
He really didn’t have a choice. The lil’ taco bender was just like a mutt yapping at his heels and he would not stop so Cruz had to respond. The attack was obviously going to take place so just as well get it out of the way now and the backblow has started for Rubio.
I don’t think Cruz could avoid the excursion. It was inevitable as long as Rubio was willing to misrepresent Cruz’s position by pointing to the proposed but rejected legislative amendment. Now that is out of the way, and Rubio is the one who lost ground.
One problem with a five-day-long mud-wrestling contest, is after it is over, it is hard to tell the winner from the loser.
