What should we make of all these polls? NBC News' Steve Kornacki breaks it down - Poynter
Briefly

There's some very big questions that kind of hang over the election and hang over the polling that it really won't be resolved until election night. The biggest one is we saw state-specific - big state-specific - polling misses in 2016 and 2020 that particularly affected the Big 10 States: Pennsylvania, Michigan, Wisconsin. Does the issue persist for a third straight election? If it does, then the polling right now is actually a lot more favorable for Trump than it looks.
Take them all in, look at the trajectory of the polls and see if they are trending one way or another. That is always a good indicator.
