Are There Trump Supporters Who Regret Their Votes?

To the point made at left:

1) There are plenty of Trump voters who regret their votes.  If that weren’t the case, it would be impossible to explain Trump’s cratering approval ratings.  Now, how many of these folks base their regret on the price of groceries, or the fact that trump continues to reveal himself as a criminal sociopath is impossible to know.

2) More important is the truth revealed in this quote from the immortal Carl Sagan:

“One of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even to ourselves, that we’ve been taken. Once you give a charlatan power over you, you almost never get it back.”
