Did Rubio/Kasich/Cruz denounce the leftist thugs or not?
No, they blamed Trump.
I am very confident Mr. Cruz at this point is looking back on his comments with deep regret.
Hard to believe media, Cruz and other candidates immediately jumped on the blame Trump bandwagon. All this while innocent folks who only wanted to attended a rally, were still being assaulted, attacked and intimated.
Ugly stuff.
Actually, Cruz did. He said they didn't have the right to SHUT DOWN political discourse but that isn't "good sound bites" for people who dislike Cruz
"I will say this: Protesters have no right to engage in violence," Mr. Cruz told reporters in Illinois, also saying the protesters have no right to threaten violence or shout down other speakers. "The First Amendment gives every one of us a right to speak, but we don’t have a right to silence others," he said. "And to the extent these protesters are organized leftist groups, whether it’s Black Lives Matter or Bernie Sanders or George Soros, or some other moveon.org leftist group, they’re simply trying to terrorize political speech." "That is not their right. It is wrong, and we need to stand against it,"
I think Cruz support has dropped from around 23 to 17 percent here in the FR Daily Caucus because of this.
