As far as getting back to original question, does anyone regret voting Republican, the guy I've been seeing (who I didn't realize was Republican because when I asked before dating whether he had voted for Trump said no (only because he didn't vote)). I said, what do you think of Trump now? And he said, well I think maybe he's made some mistakes, but I think he's smart, he's a smart businessman, he wouldn't be where he is now if he didn't know what he was doing, so I think he going to make good decisions. But when I mentioned what did he think about the fact he is now implicated in federal crimes, he got defensive and said, look I'm not political. And we had previously agreed not to talk about politics, so we changed the subject. Basically he seems totally comfortable having Trump as president, thinks he doing a good job, making good decisions (when I asked him for an example said he's going to "fix" the ACA, because it's too expensive).
One thing that I think is relevant to his thought process, is the same weekend we were talking about something unrelated (business stuff) and he explained that rules and regulations, are not absolute; t's really more about knowing the right person, and one person might tell you no, but if they know you know someone influential it will happen. Basically, only the dumb people follow the rules. Maybe he identifies with Trump?
Bottom line, I see someone who made up their mind about him (positively) on very little information (aka reputation as a successful businessman). Despite more and more "data" to look at, is not willing to examine that data or revisit their original opinion. Kind of like I made money on black, no matter how many times red comes up I'm going to keep it on black no matter what.
