That doesn’t wash with me. The democrats made it clear that they wanted to impeach him. This mobilised democrat voters and they got the result they wanted, which is fine with you.
Boris did the same thing in the GE with brexit. Giving the people a big juicy carrot which they fell for, but of course, you probably didn’t agree with that.
There is nothing to "fall for" for the US Election. They made it clear they were likely going to impeach Trump at the first sight of indiscretion. The American people in 2018 ( a more RECENT election than Trump's election) voted convincingly to give control of the house to the Democrats. There was an 8.6 % margin in the popular vote.
This is why to say that this impeachment is because they cant accept the 2016 election results or that it is trying to undo the last election/will of the American people is total folly.
The House has the sole power of impeachment, they made it abundantly clear that they would impeach Trump, and in 2018 the American people voted for them with a quite large majority. This impeachment is entirely in line with the will of the American people's view.
Even the latest average polling on impeachment show this:
