-The mainstream polls all showed Her up four over Trump on election day.
What exactly is your point though?
She won by a smidgen over 2%, which would be within the MoE for pretty much any national poll showing 4%. The topic's question was presumably for factoring in any buyer's remorse.
-I suspect buyer's remorse on both sides is almost exactly equal, so Trump would win by the same margin if the election was redone (with maybe a New Hampshire win).
You can't have buyers remorse for something you didn't buy.
-There were lots of people voting for HRC expecting something much worse under DJT than what has actually happened.
If anything, more people would vote against Trump if they had the chance. I can't tell you how many Trump voters I know who, before the election, said he wouldn't actually do all the bad stuff he was campaigning around.
