They're jumping the gun to assume the House will impeach. It is not a given the Dems there will vote for it unanimously, or with enough to clinch a majority. There are some seats that aren't deep blue, and others who are but have skeletons in their own closets or other similar reasons to leave that shit alone.
Concur.
Miss Nancy is resisting voting on impeachment resolutions. She knows it could be ballot-box poison, regardless of the outcome, and evidently there are Ds who oppose both having a vote and the resolution itself. So it might not come up for a vote. If it did, there are enough Ds opposed to it and enough
Never-Trumpers to make its fate uncertain. I doubt there are enough
Never-Trumpers who would also vote to remove Trump for Trump to be removed, so a frivolous impeachment resolution plus a defeat in the Senate are not likely to look good to ordinary normal voting people.
