they are not backing off, this is just a smoke screen. It is too early to have a great effect on the 18 elections, they want to stall this through the summer and begin anew after Jan 1st.
They don’t want him impeached they want him impotent. If Trump goes he is replaced by a more conservative VP who understands how DC works, could probably get things done, has more self control and therefore would be harder to smear. And God forbid what if Pence chose a conservative woman as his Veep? The democrats know Trump is more use to them in office being pilloried and attacked daily. Throw out impeachment, scandal, the Russians anything to keep the meme of a damaged president on the front page, FB and twitter, but don’t actually impeach and take a chance with his replacement someone they can’t really tarnish as easily.
Not sure they can chill the summer activities already planned by the Soros lieutenants. The anti-intellectuals would have nothing to fun to do this summer if not for peeing in the streets and practicing their intimidation tactics against whites. Not sure these adult street urchins will comply.
Perhaps they have figured out a crowd can only throw so many bricks and burn so many cars, for just so long, before they need a nap.
