This sort of non sequitur is dangerous to democracy.
Given the GOP's willingness to strong-arm twitter and facebook (remember Trump tried to have it investigated by the DoJ), I feel like regulating companies due to being a political enemy is exactly what I'd expect the GOP to do. Perhaps it's the one time you can be sure they'll start regulating.
From my perspective, the democratic party is constantly talking about how bad Citizens United is (and I am very sympathetic to that) while taking millions upon millions from large companies and wealthy individuals.
