The process of repealing a president (impeachment) is a political process. Republicans could do it at any moment, so every day they don't is an endorsement of what the president has done, continues to do, and even what he threatens to do.
This country is founded on the principle of being able to spot the pretexts (tariffs, terror-driven deportation, selective refugee status of whites fleeing black majorities, dissolving of social nets, rampant corruption) to monarchy-authoritarian leadership.
The current DNC is waaay too weak and uninterested in pushing back against Trump for this to realistically happen. They are complete enablers of this slow fascist takeover. Your only hope now is for the democrats to experience a "tea party" of their own, and have actual leftists take the reins before 2028. Seems highly unlikely now.
