Emerson continues to be a mess, and NBC/WSJ has regularly been one of Trump's best pollsters. They even had him at 46/52 before the midterms, and we saw how that turned out.
Still, Trump appears to be experiencing that upswing in approval heading into election season that we've seen in every President since Nixon (sans Carter).
Probably what's happening is the few NeverTrump Republicans are realizing that they'll have to vote for either Trump or one of the Democrats, and they hate the Democrats, so they might as well get used to supporting Trump now.
