There are many people of Christian faith (or family backgrounds) who live their lives based on the 10 commandments. I don't practice my faith as per going to church every week but I do practice the principles. Those people you're referring to aren't Christian. They're just trying to fool people.
Everyone who voted for him, everyone who didn't vote to keep him out, every member of the administration, every elected Republican (federal & state) who isn't fighting back – that's a lot of untrustworthy, unprincipled people
A lot of frightened people who see their way of life disappearing before their eyes voted for him. He vowed to lower prices not start trade wars. A lot of them never saw this coming. Democrats weren't helping them and they were losing hope. Not everyone saw this evil.
