Both Levin and Cruz will endorse Mr. Trump. There is NFW either will take any steps that help The Beast. There’s a long way to go in this election cycle and both are trying to push Mr. Trump away from Bernie supporters and closer to grass roots conservatives.
You can’t unring the bell of a post primary months long Hillary enabling tantrum by Ted Cruz and his supporters. Sore loser Cruzers having a tantrum on the floor of the convention in no way helps Trump beat Hillary.
I’m more concerned about McConnell, Ryan, Preibus, Bush and their Chamber of Commerce pals undermining Mr. Trump than anything Sen. Cruz can do.
