It shouldn't be that hard for you to show some evidence things would be different then. There is nothing indicating a stronger preference to vote has anything at all to do with which direction you lean. More and less does not equal right and left, so the burden of proof is on those who claim it is relevant. Yet polling indicates things would have gone pretty much just as they went.

I don't know if voters and non-voters have the same political leanings. It isn't something I've ever looked into. My observation was merely that measures of statical confidence assume random samples. Extrapolating from a non-random sample can give odd results. But this isn't a research paper, so it doesn't much matter.

You are reading too much into it. If I study runners, I should presume the study will apply to those who don't run should they become runners, unless I have evidence otherwise. All the more since many runners were once non-runners. It's not obviously a confounding factor, that would need to be demonstrated. And as I and others have already said, the actual studies indicate the results would have been the same in this election.
