It was Texas Trumpers that shared a similar dislike to Sen. Cruz that @Right_in_Virginia @Frank Cannon and last but certainly not least @TomSea does that causes his winning by 2% and not 10%.
So screw you 'fake' Cruz lovers'
Ted Cruz was plenty popular in Texas, and nationally for that matter given the strength of his Iowa campaign, until Trump did his best to destroy personally both Cruz and Cruz's family, including the morning after securing the nomination at the Republican convention. There was no long-term strategy or insight behind Trump's behavior, no "flying nine dimensional invisible stealth jedi chess" that only Trump was smart enough to understand, just pure narcissistic malice. Some of Trump's defenders in the media have suggested that Trump deserves the credit for Cruz's victory because Trump campaigned for Cruz recently; at best Trump was merely helping to solve a problem that he had previously created, a problem which could have put the Republican Senate majority at greater risk.
To Trump's credit he was the first to make illegal immigration a central issue in the 2016 campaign, he has demonstrated to the Republican establishment that their base wants a fight, he's taking a strong position on regulation, and he's been true to his word on Supreme Court nominees. But the argument that there is simply something wrong with Ted Cruz is a canonical example of viewing the entire political world through the funhouse-mirror lens of exalting every word Trump speaks and every move he makes.
