Sure. If
-There are no games being played on ballot count watchers
-democrat secretary of States don't change the voting rules
-There are no mysterious boxes 'o ballots found under a table
-There are no power outages, water main breaks, sudden eruptions of ebola at the counting sites

...then most would agree things are fair.

So then there will be riots from the right, and they will not agree that things are fair.

There are always things that people will claim are "games" being played on ballot count watchers. There's thousands and thousands of polling places and canvassing boards, and all of them have rules and procedures - and some people somewhere won't follow them and be escorted out. There were no mysterious boxes o' ballots found under a table (see below link). The election is conducted in literally thousands and thousands of buildings, ranging from old municipal buildings like libraries and schoolhouses to brand new government offices - there will be stuff that happens in some building, somewhere no matter what.

So if you're already prepared to seize on any of that sort of stuff - which happens in every national election and will happen again for certain - as evidence that things aren't fair, you're just saying ahead of time that the right won't believe that the election is fair unless Trump wins.

You're asking me about conditions for a riot. Any riot would occur as a spur of the moment thing; it's not going to play out in a courtroom first.

Right. But you set out a whole bunch of things that would set off a riot from the right. Most of those things didn't happen in 2020, but the right claimed the election was unfair - because people claimed they happened, and by the time it got into a court and the parties were forced to admit in court that there wasn't any fraud in the counting, it was too late. A huge chunk of the right believed it anyway. It didn't matter that those things didn't actually happen - the right believed it (you still believe some of it), so they think the election wasn't fair.
