That narrative makes sense if you assume that every politician is a "corporate tool". Trump clearly didn't start out his role as a public figure being on the extreme right. I don't think that he personally holds those views. As to why he bent over backwards to embrace the far right, and evangelical Christians, will probably always be open to speculation. I don't claim to know but I have ideas.

I hope he's doing it for the right reasons. But one thing to remember is that the ACA was not the Democrats first choice. People seem quick to forget that the Republicans were so unwilling to compromise on every level over the last 8 years that they literally shut the government down, and denied the public a supreme court appointee. In that regard I'm glad to see the kinds of statements that Trump made in the recent congressional address. If he is really a trojan horse for the American people then he will be someone who speaks towards the center and not to the far right.
