Illegal Use of Absentee Ballots happened almost in a literal way, since state GAs and Governors changed electoral laws without the authority to do so, disrespecting the courts and their own legislatures, this is discounting the obvious use of Mail-In ballots for fraud, using false adresses in government buildings, fabrication of ballots and so on.
Oposition Observers were ejected from counting precints, there are hundreds of reports of such happening, video, photos, and even lawsuits asking for the observers to be in a distance close enough to actually observe anything, you hadreached the point of having pricints that obstructed their windows so they could not be observed.
North Korean style turnout also check, since there were counties where the turnout exceeded 99% in the states allegued of fraud, some might have exceeded 100% having more votes counted than the registered population in voting age, you also see massive spikes in turnout that far exceed 40% shifts in areas that show no history of doing so.
Mobile Ballot fraud, is almost laughtable, since Biden got batches after election day of nearly 100% ratio in votes in Mail-In ballots, that swept in a instant a two digit lead Trump had accumulated during the whole day, these present an almost miraculous distribution that is in no way consistent to the known data of registered and returned Mail-In ballots for both parties in these states, the text about Ukraine talks about huge increases in the use of such ballots, in this election they were increased in some precints by more than 1000%.
Computer Data Altered absolutely checks, and in every swap of vote, every shift, they were all in Bidens benefit, many machines were reported to "mulfunction" this election, shifting thousands of votes between candidates that were only found after maual recount of the ballots.
Reports of fraud are pilling in with hundreds of sworn affidavits, Mail workers, Observers, people alleging to be forced to backdate ballots, people withnessing the preserce of perfect printed ballots with perfect circle marks, there are hundreds of whithnesses to the schemes that happened in local precints.
literally all of those things caracterize a fraudulent election that happened in a third world coup, these are only the similarities to Ukraine, we didn't even talk about the suspicious pauses in counting that happened in elections like the ones in Venezuela and Bolivia.
