This is what's coming:
If Drumpf fires Mueller, Republicans are going to impeach him and remove him from office. This is the "red line" they've been talking about.
If he doesn't fire Mueller, Mueller is going to present damning findings and give Republican officials cover as "findings that we can't in good conscience ignore." Then, yep, they're going to impeach Drumpf and remove him from office. Mueller is cooking up their excuse, their rationale. He's a fucking Republican, for crying out loud. This happened with Republicans having all the power.
There's a reason you see almost zero Republican officials pushing back against the Democrats and a reason Drumpf has started whining on Twitter about having no protection. Even Sessions threw him to the wolves.
I'm stocking up on popcorn. You dumb rednecks don't see it coming.
