I think it proves Cruz is a suck up that will never speak hard truths. A damned low life if you ask me. The ONLY answer to that by any American politician should have been to scold the violent mob.
Cruz sided with the mob and tacitly told them he thought they were justified. Low down and no good of him.
In thee cases you cannot back down. If the mob smells weakness it will win. Cruz is showing us what a whimp he is and what kind of president he would be.
