The Donald seemed to take up the Marco Rubio criticism of Cruz in an interview with Wolf Blitzer by accusing Ted of being in favor of amnesty.
The only way in which you can make any semblance of sense out of his comments is if you take the Rubio campaign argument that Cruz was for amnesty when he tried to amend their bill, but Cruz has repeatedly denied it, saying that it was a poison pill tactic to kill the bill.
Even if you don’t want to concede that Trump is being disingenuous, he does seem to be unable to deny that Ted Cruz has now fallen to his right on illegal immigration. While the Donald will let back in those he deported as long as they’re “good people,” the Cruzinator has said he would not let one back in. Maybe that’s why Trump had to resort to the Rubio criticism.
