Well I don’t think they care if these actions Impeach Trump or not...that’s not their purpose in this. It’s the Dems “tactic’ to keep the media engaged in it in order to sway the voters away from Trump for 2020, reclaim the 2016 vote, but primarily to prevent any focus on the huge number of Demorats own corruption out of the news.
His supporters will remain his strong supporters.
His detractors will still hate him.
And the few left in the middle, will not vote in the election on the basis of the impeachment or no impeachment.
They will vote on what most voters always voted on and that is the booming economy, historic high employment and higher wages.
