Are you saying that everyone who voted for Trump knew he was lying when he promised healthcare for everyone, better and cheaper than the ACA? That everyone who voted for Trump knew he was lying when he promised not to cut Medicaid, either in dollars or in persons covered? That everyone who voted for Trump knew he was lying when he promised to preserve coverage for pre-existing conditions? That everyone who voted for Trump knew he was lying when he said he was pro-life, that he would protect healthcare for women and children? I could never wrap my head around the notion that anyone believed any of those things, but some people did. I know some of them; and they know they were duped.
Of course, Trump has a base of supporters who didn't believe any of those things and don't care about them. These are the idiots who think Mexico is going to pay for a wall; the bigots who want to exclude Muslims; the racists who want to deflate minority voting; the science deniers; and the very, very rich.
