The train of comments of the video, dated the day of and the day after, prove my recollection correct. It was a breathtaking backstab, and should have earned him an exit visa from the GOP.
That said, I do think that Cruz would do himself a whole lot of good if he launched his 2018 campaign with something like an "I was wrong" campaign. If Cruz begins with apologizing for his 2016 speech, admitting that Donald Trump achieved breathtaking results improving the economy, and vowed to get behind him 100% in implementing the remainder of the agenda through 2020, he'd all but wrap up the Texas vote.
