Republican pols couldn't be happier to see Trump acting like a dictator:
They love dictators and hate the Constitution
It lets them ignore that pesky legislating they've always hated and focus on Stunting for their voters all day
They've wanted to kill every program and department that helps anyone but rich white assholes since they were created, but never had the votes to do it and know they never will
Turning the US, the country whose founding is usually credited with kickstarting the post-Enlightenment democratic revolution in world politics, into a dictatorship is the ultimate "Stick it to the Libs" move.
These last few weeks have had Everything, from their perspective, and all they've had to do is sit on their asses and tweet about it.
