When an administration enters office with a stated goal of, for the first time in America's history, literally bringing down our very institutions, it's certainly fair for reasonable people to be concerned. At best, this would create serious disruptions and losses for millions of Americans. At worst, who knows. It doesn't help matters when that administration represents a swath of the country that essentially operates in an alternative reality.
Did everyone who voted for Trump want this? Of course not. Many are just not paying attention to the political minutiae, and they're used to a sclerotic, do-nothing government. That's understandable, kind of.
So, we just watch. And, assuming that our electoral system and access to voting still exist intact in the next couple of elections, we'll be able to voice our opinions on the results. The one thing we know is, ya never know.
