The problem is the Left is too reflexsive and hyperbolic. They think that their little astroturf axis of Dem politicians, deep state bureacrats, SJW fascists, the Hollywood crowd, lefty CEO's, and university academia can by leveraged by constant and relentless media attack into some sort of political wave that will wash away Trump and all the right wing. They have become so demonic in their thirst for political blood and bodies that they have lost all sense of strategy.
Problem is to Main Street America they just look like a nutter echo chamber whipped into a teacup frenzy. The brass ring of impeachment is an overreach and a cross that they are going to be impaled on if they keep it up. The only way Trump and the GOP will have problems is by their own hand. As of right now they have total control over their destiny. They just need to ignore the clap trap and get things done.
