Just as with Obama, I don’t see either House coming up with the necessary 2/3 majority vote to impeach and remove Trump from office.
So these Democrats must be politicking.
Corrections, insights welcome.
They’re trying to keep Trump, in particular, and conservatives, generally, radioactive to as many as possible for as long as possible. This will get more and more difficult as Trump racks up successes, and conservatives discover that they can express their views publicly, without fear of reprisal.
