The thing of it is the dims face practically no consequences for anything they do so why not just make up Russians and dossiers and impeach the President for nothing...make up the news..fake news ...
They probably don’t care if they lose seats.....Pelosi ..Schumer ..Schiff are not going to lose their seats...
I think this is a way the Democrats have discovered that they can CONTROL both houses of Congress by simply tying up the Senate with baseless impeachment hearings. It keeps the spotlight on THEIR accusations, smearing Trump, repeated endlessly over the mainstream media during this election cycle all while denying the Senate the opportunity to function in their normal capacity to approve additional Trump appointed judges to the bench.
They have no problems dragging this situation out.
