In the week July 26-Aug. 1 there have been six polls conducted nationally. Three show Trump in the lead by 2-4 points, three show Kamala up 1-4. Any poll that ever shows Trump with 50% or over I immediately disbelieve since he has never gotten more than 47.8% of the actual national vote. Forbes/HarrisX July 26, Trump 51%-49% and Harvard/Harris July 30, Trump 52%-48%, meet the said criteria for my circular file cabinet.
Basically, I don't have faith in the recent national or swing-state polls.
