"if the GOP wins the House?" First of all, why wasn't this and all the other promises kept when Republicans had both houses and the presidency? Secondly, I have my doubts the Republicans will retake the house and they are in fact in danger of losing the senate too.
Trump and the Republicans blew their chances. Making the same promises they didn't keep a few years ago is not going to win over voters. Fool me once, shame on you. Fool me twice, shame on me.
