If your memory was “good” then you would have serious concerns about Trump’s flip-flopping on EVERY issue during the last 4 months-2 years.
I read Trumps 2011 book. His positions on most issues are pretty much the same now as they were then. Cruz voted for the Corker bill before he railed against the Iran nuke deal that resulted from it. Cruz voted for cloture on TPA before he voted against the actual bill. Cruz proposed expanding H1B visas by 500% until he changed his mind in November. Those are not flip flops in your view?
