So, if you spend most of your time imagining various scenarios how the world would end if Trump wins, this is an important information for you: Publish a book, and transform your fantasies into a source of income.
(Heck, even if you are a Trump supporter, you could still collect the stories from the web, and publish them.)
Don't procrastinate, the time is limited, and the opportunity can also disappear if other people publish too many books before you enter the market. If you can make the book in a week, the quality doesn't matter much, you can ride the wave.
Disclaimer: This comment is not supposed to be pro-Trump or anti-Trump, but "how can I profit from this situation", similarly to how people discussed how one could have profited from the COVID-19 situation.
Apart from Trump making the obvious and true point that mail-in ballots are ripe for fraud, all the evidence for people not accepting presidential election results seems to be from the Democrat side. For example:
This anxiety about whether Trump would concede seems to include a significant element of projection.
inb4 "So you're saying Trump is a good man, a good president, an honest man".
No I am not saying that.
I think you may be conflating two very different meanings of "not accepting". On the one hand, there's "X shouldn't have won"; on the other, "X didn't really win". The things you quote seem like they're much more about the first, and the book here is speculating about a claim of the second.
So, of your four things: the first, in the actual instances I've found, is "I wish he hadn't been elected and don't think he represents me" rather than "he is not really president"; I don't know what the second means, unless it's the same as the third; the third, so far as I can tell from the specific instance you selected, says no more than "Clinton will probably win" which has nothing at all to do with your claim; the fourth might or might not imply "not legitimately elected" but was not the partisan thing you want to represent it as.
