Well, I’m a Canadian, but my concerns about US election security is pretty much as in the quoted posts. Voter fraud from voters is virtually non-existent, but voter disenfranchisement is absolutely huge. And disenfranchisement is being driven entirely by the GOP, it seems.
Why do I care? Because of the “End of Democracy” thing, really. Democracy only works when people believe it works - it’s literally a huge magic illusion. And the events of the last two decades have done nothing but erode people’s confidence in democracy. Whether it’s Republicans spinning tales of millions of illegal voters, or Democrats pointing out the adverse affects of gerrymandering and disenfranchisement, the cumulative effect is to decrease faith in US democracy on both sides of the political scale.
That can’t continue indefinitely. At some point, it will break, and I fear that point is far closer than a lot of Americans are willing to admit.
And this matters to Canada because when the US descends into violence and dictatorship, no matter who fires the first shot, Canada is going to get sucked down the drain with you, no matter what we actually decide to do.
The rest of the world cares for similar, although perhaps slightly less intense, reasons. The collapse of the US will not be pretty, and will not leave anyone unscathed.
