I think they well anticipated a Bad Trump, and have checks and balances built into the system that would handle him well.
What they didn't account for was Bad Republican Senators, who wouldn't convict his impeachment, Bad Republicans in general who would continue to support him and, especially, Bad Republican voters who would keep voting for him.
Meh, I don't think it's just Republicans. I don't think they accounted for the undue influence that the parties have gained. When the nation was formed, it was largely a collection of congress critters that each represented either the interests of the people in their district, or the interests of the state as an entity. Each of them was elected and expected to perform those duties honorably. Parties existed, but were more of a collection of people with shared ideas working together to drive consensus, and there was a lot of disagreement within the parties themselves.
Nowadays, we have congress critters whose first loyalty is to their party - not to their constituents or their state. Nobody foresaw the possibility of two non-governmental bodies gaining de facto control of both the legislative and executive branch.
FFS, we the people don't even get to have a say in who our presidential candidates are. We're given a short list that the party has decided we're allowed to choose from... and then the overwhelming majority are run out of the race after preliminary consideration in at most three states. The vast majority of the citizens of the country never got the opportunity to voice their preference for candidates in this race.
