Because there is no trust.
That's nice, the Democrats don't trust you either. Regardless, no judge is going to consider a recount based on that reasoning.
4 years of illegalities and a dog and pony show impeachment against the incumbent.
So where are the indictments? Regardless, has nothing to do with the election, so is not "evidence" of anything.
Then again, maybe that is why Biden picked Harris as his running mate, he figures that there is no way Republicans would try to impeach him (as retribution) and risk Harris becoming President. (To be clear, this is a joke and not intended to be taken seriously).
Plus countless videos of people throwing away/finding thrown away ballots.
That's nice, but is evidence of nothing. In fact, in many cases I suspect people trashed a mail-in ballot they requested but didn't use, they voted in person instead, and then put their own ballot (and maybe those of friends) in the trash to make the video. Don't get me wrong, investigate them, but the videos seem very questionable.
Poll watchers disallowed to perform their duties as applicable by law.
And those cases are being heard in court and, if necessary, corrective action has been taken. Though, at least some of the allegations of "not being allowed" has to do with too many poll watchers already in the room -- that is not a failure by the state, but by the campaign (too many poll watchers scheduled for the same time).
Counters using pens to alter ballots,
I'm not aware of any verified claims. Instead, videos I've seen are of a person darkening the markings of the ballot so they can be scanned by the machines, and paired with another person that is ensuring that only previously marked boxes are being darkened.
Interesting that you think they would have a person, on camera, altering ballots with observers watching. I'd be interested in seeing the evidence that he was altering the ballot -- particularly without "erasing" any marks.
crumple up and throw away ballots.
Were they legal ballots? Or was it some other piece of paper? If it was a ballot, I'm guessing one of the observers removed it from the trash as evidence? It is amazing how there have been so many false stories about "fraud" in the election on social media,
such as this person who claimed he threw away ballots.
Miraculous 4am votes pouring in for the other party.
No miraculous "4am" votes. They kept counting votes overnight, were counting Detroit ballots, and got a majority of votes for Biden. Not only did Detroit go overwhelmingly for Clinton in 2016 (almost 70%), but they were counting mail-in ballots, about 2/3rds of which nationally were requested by Democrats, so you'd expect almost all of them to have been for Biden.
An entire political party that has stated they must win at any cost.
That seems to apply to Trump and Republicans as much as it does to Democrats.
