I disagree, these "moves" he's making appeal to the MAGA crowd, sure. But he's doing everything he can to alienate a huge segment of voters. First and foremost women, whom unless they're popping out multiple kids with their husbands, they basically have no rights to him. Then you have the gay community, which needless to say despises him, followed by the black community who seemingly doesn't like him either. Why should they? He wants to erase their history.
On top of that, you have middle of the road folks. Someone who is fiscally conservative like me but hasn't been brainwashed by this "everyone but me is a pedo" nonsense can see right through this, including in the area of economics. Tax holidays are only shown to pull forward demand in the short term, while causing larger deficits in the future because massive spending under the guise of record budgets. This is the same crap Republicans have been doing forever now.
So unless you're a far right white or Latino, you're probably not voting for this guy. I'm hoping Trump runs as an independent to squash any other chances he has.
