Maybe I'm jaded but I see the polls as a tool to set up the mindset that this could 'go either way' and put the election in steal range.
I live in a relatively sane part of the US, so those in my 'bubble' are not supporting Harris.
Government employees might because government expansion is opportunity for them to move up (and collect more of our tax dollars).
Anyone who ever paid their bills in the last 10 years who earned the money would, given even a high double digit IQ, see that this Administration and its policies have hurt them economically and otherwise, and that was with the relatively competent (if crooked) Biden at the helm for at least part of that. Harris bodes them no better, and you don't have to be a genius to figure that out.
Unfortunately, it appears that thinking for yourself is no longer an American trait. Maybe the illegals will hammer the detriment of a Harris Administration home before the election.
