When did Cruz go after Trump? I hope you’re not referring to the little Happy Days clip.
I was referring to the statement he made during a private meeting with donors about how he did not trust Trump handling nuclear weapons. I noticed that all the Cruz supporters claimed they did not see anything at all like that in his statement. However, during the debate, Cruz was asked about it by the lady in the same exact terms I just mentioned. Cruz immediately and generously enlarged the doubt to include everyone on state. Of course, in the original, he only included Trump and Carson, his main two opponents.
He also implied/said that Trump wanted to send “jackboots” to every home in the United States in search of illegals.
I, of course, don’t follow every word that Cruz says. There are probably more.
As for the eligibility controversy, that horse left the barn before Trump ever declared his candidacy. Obviously, if Cruz had the paperwork to end it, the paperwork would have been released. I say that based on what others have said on the site with the same circumstance.
