I had read that at the time it came out. The fact that you're looking at it and seeing fraud tells me a lot. You're looking at the world from the perspective that you believe fraud must have occurred and trying to justify it off of truly absurd distortions of the facts.

I don't have a ton of time at the moment, but I'll address your examples.
-- mailing out ballots to everyone when the law didn't allow it
This presumably refers to Nevada. USA Today fact check (https://www.usatoday.com/story/news/factcheck/2021/02/05/fact-check-viral-post-makes-false-claims-nevadas-election/4392902001/)
"Our rating: False
The claim that Nevada's 2020 presidential election included cases of duplicate voting, dead voters, fake addresses and noncitizens voting is FALSE, based on our research. The claims in the post are based on a failed lawsuit where a district court found that no illegal votes were cast and counted or that any legal votes were not counted. Biden won Nevada's six electoral votes and those results were finalized by Congress."
-- extending deadlines for the receipt of mailed ballots
I assume this refers to Pennsylvania, where far fewer ballots arrived after Election Day than would be required to change the outcome of the state (https://www.inquirer.com/politics/election/pennsylvania-mail-ballots-counted-deadline-supreme-court-20201111.html). The Supreme Court also held before the election that this change was ok, so accepting such ballots was not illegal.
-- prohibiting election monitors from monitoring the election
Michigan, Georgia, and Pennsylvania I presume. These cases came up in court over and over again and lost in court. Here's an example of how that argument is absurd in Pennsylvania: https://www.cnbc.com/2020/11/17/trump-campaign-loses-case-on-philadelphia-vote-count-observers.html "The court noted that state law mandates that observers be permitted to be “in the room” during ballot counting, but leaves it up to county election officials to determine a minimum distance, if any, from the ballots being counted. A witness in the case had testified that even at the distance he was kept, he could see the counting process."
-- voiding signature and postmark verification
Quick search says postmark issues could be Michigan. Fact check: FALSE. Side note: Don't ever listen to what Project Veritas says, because it is misinformation meant to deceive you. https://www.politifact.com/article/2020/nov/05/allegations-usps-election-fraud-michigan-dont-hold/
-- ballot harvesting
I don't know what contested state you might be referring to here, but Georgia seemed like where I might have heard this one so I started there: "The Georgia Secretary of State engaged MITRE to assess the Georgia electoral process and results of the 2020 U.S. presidential election," said Jerry Hogge, senior vice president and general manager of MITRE Public Sector. "Based upon our analysis of the data provided by Georgia’s Secretary of State, we have concluded that there are no indications of alleged ballot harvesting." https://www.thecentersquare.com/georgia/analysis-shows-no-signs-of-ballot-harvesting-in-georgia-elections/article_4b919d58-446f-11eb-b1db-877d4752b043.html
-- curing ballots
This one seems like Pennsylvania. Not illegal and not enough to change the outcome. https://www.factcheck.org/2020/11/ballot-curing-in-pennsylvania/
"It wasn’t only Democratic counties that “cured” ballots, as opposed to Republican ones that didn’t. All counties got the same guidance the night before the election instructing them to notify political parties and update the ballot-tracking online system about ballot errors, thus allowing voters to cast a provisional ballot on Election Day.

Some counties notified voters, and some didn’t.

Republicans have lodged several challenges about the so-called “cured” ballots in court, arguing that counties that refused to “cure” ballots were simply following state law and a state Supreme Court ruling that prohibited it. Democrats say the guidance was clear, and perfectly legal.

But even if the courts were to reject cured ballots, election experts say there were too few of them to make much of a dent in Biden’s slim lead in Pennsylvania anyway. Biden led Trump in Pennsylvania by about 60,000 votes, according to vote tallies as of the morning of Nov. 13."

You seem to be under the impression I didn't see all this stuff back in November. I did. It was garbage then and it's still garbage. Trump and his people were lying to you then and you fell for it. The reason they lost all those cases is because they didn't have the facts or the law on their side. You can choose to continue to believe untrue things or you can read non-partisan fact checks and correct your misconceptions. Up to you. Have a nice day.
