Unfortunately, people were never going to drop everything for this over what has essentially been a seesaw of normalization. We've had many many many months, going on years, of "we got him!" into "Oh wait nevermind" over and over. People get bored, or overwhelmed, moved on. They're not going to organize effectively in less than a week. If the media just left the damn investigation alone until now, maybe there'd have been a shot via pure shock factor. But we, as a country, are just innoculated to Trump's wavering legal status now, and so unfamiliar with the law as it pertains to those in power, that to anyone not following politics closely, this isn't a bombshell. It's just waiting for the other shoe to drop. You really need several weeks of planning for an effective protest given the circumstances, which, well, you didn't get here.
To be clear, I think Trump absolutely should be impeached. It's mostly symbolic, but if we want to put any stock in our so-called democracy not just being an oligarchy, we need to follow the rules so they can't be flaunted later. The rules say, in this current situation, you must impeach. Ergo, if Trump isn't given impeachment proceedings, you set a precedent for not holding corrupt presidents accountable. I absolutely believe we're getting someone far far worse than Trump after whoever is the next president (failing an absolute cultural and educational revolution) and we need to be able to take them down.
That in mind, I don't say lightly that this entire protest was just a bad idea. It was never going to amount to anything given the situation and the time in the oven it was given.
