Nope, not unless he follows it up with other good moves. He has proven untrustworthy already. This is too late in coming.
"proven untrustworthy" = "after fulfilling hundreds of promises he dared make a deal with the Democrats to get Harvey/Irma funding through ASAP".
This is why conservatives always lose.
Number one, you either support corrupt scumbags like McCain, Romney, George W. Bush, for whom you make countless excuses over. OR you support "hard line" ideologues, who aren't hardline at all, like Ted Cruz and Breitbart's BS about his "he never voted for H1B increases! He never wanted to legalize illegals!" (even though he wanted to triple it and to grant all illegals permanent residency) immigration stances.
Basically you're almost totally useless! It's a damn good thing that the base of Trump's support ISN'T these "conservative" ideologues. They're regular people with common sense, not howling at the moon over Free Trade.
