Trump’s political instincts aren’t what they used to be. Giving ground on an issue, no matter how unpopular your position is, only helps your opponent because it tells low information voters “actually the other side was right about this all along and I’m bad on this issue.” Unlike the DNC, which has never seen a position it would defend, the GOP usually has the political savvy to barge through, polling be damned, since the only thing the american electorate respects is strength. Glad to see them screwing the pooch, especially on this issue, but VERY odd for both Trump or the GOP overall to make this kind of DNC-flavored error of spinelessness that only helps the other party both structurally on the issue and during the election at hand.
