The Dems have promised to continue their shamvestigation fishing expeditions. They seem to forget that US voters can shut them down, and I think the current fiasco is making that likely.
What makes you think that the Democrats care about the voters? They have never accepted the results of the last election - because the Republican won.
And now they are pursuing a multi-pronged strategy which includes trying to override the Electoral College by means of a state legislature-led end run around the Constitution. If that fails, they will insist on the illegitimacy of a Trump victory in 2020, while continuing to pursue grounds for impeachment, even after the current attempt falls short. If Republicans take the House and retain control of the Senate, look forward to endless legal challenges, promoted by Democrat state attorneys general, and funded by Democrat billionaires.
If you haven't figured this out yet (though I suspect you have):
the Left never stops in its pursuit of power.
Republicans crave normalcy, in process, procedure and rules of governance, because they are
normal. The Progressive Left is possessed of no such interest, and never has been.
