We’ll start with politics, and this probably has the political establishment quaking:

“How likely is it that cheating affected the outcome of the 2020 presidential election?"
Majority, Likely: April 2021 - 51% ... Oct 2021 - 56%
DEM: Now 32% - Was 30%
IND: Now 54% - Was 51%
GOP: Now 84% - Was 74%
All Voters: 56% - Was 51% https://t.co/KJoK8ZDCSG

Rasmussen Reports @Rasmussen_Poll
OK, I’ll admit that the Dem line is within the margin of error, and the Indie line is close, but still …
Now, Covid. To get this you need to understand that the L’Express article is about Peter Daszak, and Richard Ebright is talking about the gain of function research that Fauci and Daszak were pushing at Wuhan:

"Richard H. Ebright, a microbiologist at Rutgers University in the United States, told L'Express. For the researcher, these experiments are like "looking for a gas leak with a match". "

President Trump stated today "If we don’t solve the Presidential Election Fraud of 2020 (which we have thoroughly and conclusively documented), Republicans will not be voting in ‘22 or ‘24. It is the single most important thing for Republicans to do." This was reported on Powerline blog, and the article and most of the comments took this as yet another chance to denigrate Trump. They misunderstood, so I will translate: "C'est la lutte finale..." These words from l'Internationale indicate we are at a crucial point. The Biden presidency seems to be a 'fait accompli', and if it is possible to steal an election in such a blatant manner and there are no mechanisms to challenge the steal, expect all future elections to follow suite. I assume the Rasmussen poll to be on the low side, and add to this that there are between 20-30% who are surely delighted that the election was 'fortified' to achieve the desired result. For me the most significant indication of the steal is in the cover-up, going all the way to the Supreme Court. In 2000 Gore held things up for weeks looking for hanging chads. In 2016 Jill Stein had full access to all materials, something President Trump couldn't get in Wisconsin even after putting up a million dollars. It is possible President Trump has a way to correct what happened, but I am not encouraged by the reaction of those who lament the Biden presidency, but are not inclined to acknowledge Trump as the leader they wish to follow. Why should he go out on a limb and invoke legal measures never before employed to save a country that doesn't want to be saved, at least not by him. He would need massive support when the enemy cries foul, and the Washington establishment will fight this tooth and nail. If Americans are comfortable with the status quo this occasion will pass, and Republicans will not be voting in ‘22 or ‘24, not on his recommendation, but because it will make no sense to vote when the system is rigged, and maybe by not voting we can indicate that we do not give our government any mandate.
What Percent does it need to believe the Fraud Happened in 2020, to have major changes?
More and more in coming out everyday. My guess is the strength of the feelings there was fraud has increased dramatically.
And what is interesting from a social viewpoint, is this is part of shifting the US from a high trust to a medium trust society. The voter fraud is only one data point. Belief about Covid from the CDC / Government / Experts. And belief in the press. And politicians in general. Belief in a fair justice system. The people that used to be the most trusting of all, play by the rules, etc. probably GOP, and now having their world view / trust, shattered.
I wonder what will happen if the Dominion Suits on Libel Fail. Supposedly the Dominion Employee that was antifa's deposition was a huge failure.
And more is coming out on how the 2020 election was tilted. Molly Hemingway's new book, "Rigged" helps:
