I've seen some bloviating about this August reinstatement and went looking. Can't find any source that has Trump saying anything about it. MyPillow Mike Lindel has, Sidney Powell has said if the election is overturned, Trump would be reinstated, but I can't find a direct quote, writing, or video from the man himself. And it's a safe assumption that if there was, it would be blasted out with the numerous articles about this new "big lie".
In the search, I came across this, a nice reminder of why polls suck.
https://www.prri.org/research/qanon-conspiracy-american-politics-report/After polling about 5500 people, these pollsters and the "journalists" who reported the numbers extrapolated that 15% of Americans believe "the government, media, and financial worlds in the U.S. are controlled by a group of Satan-worshipping pedophiles who run a global child sex trafficking operation" Of course, a larger percentage of the polled Republicans believed this (23%), surprisingly 26% of polled protestant Hispanics believed that as well, as did 18% of polled Mormons (who may very well know due to direct connections
)
Polls are more pointless now than they have ever been, IMHO. 5500 people is a minuscule percent of our over 330 million. Add to that skewing by the pollsters to get the headlines they want (nothing new) plus people who just like trolling the world (little bit newer, or at least more wide spread), and you get nothing but numbers that tell people whatever you wanted to tell them in the first place.
