I take a balanced approach to reading the tea leaves. Looking at the fundementals such as early voter turnout, the keys system of Allan Lichtman, with much less interest in polling.
I've got my own predictions now:
Harris will win Pennsylvania and Georgia.
Harris will win the electoral vote but narrowly.
Trump will claim that he won very early well before the electoral count is certain.
The maga fascist deep state of anti-democracy will fight very hard with an army of lawyers to create social unrest, even violence to overturn their loss (as they did last time but this time much better prepared so BEWARE!) up until January 20 when Harris will be inaugurated.
Needless to say I could be wrong.
As far as the psychology of the polling posted here, it could be argued such numbers will encourage more Harris voters to turn out (as it's so close within margin or error) and Trump fans to stay home thinking he's won anyway.
Cheers.
