So stop saying it.
The impeachment proceedings may be ill-advised, and end up being a political windfall for the Republicans. Time will tell. But it’s not a coup.
The Democrats have certainly demonstrated that they want to remove this president from office; this has seemed to be their intent, one way or another, essentially from Day One. But this is not a coup.
The chance is strong that the House will, almost completely along party lines, vote to convict the President. But this is not a coup.
The Senate will likely not vote to remove him from office, though one writer has written about one surprisingly easy way to see Trump removed from office. I don’t expect to see that happen, but even if it did, it’s not a coup.
And those who claim that it is, following the lead of some talking head somewhere on talk radio most likely, discredit and embarrass themselves. A coup is defined as “a sudden, violent, and illegal seizure of power from a government”. This is none of those things:
So complain about the process; dispute the manner; interpret the evidence or lack thereof as you might see fit. But for goodness’ sake, do us all a favor and quit saying that this is a coup. Because whatever it might be, it is categorically and certainly not.
