Soft coup is the phrase you're looking for. This doesn't look like what you maybe think of, when you think of a coup, but it is an attempt at a conspiracy-based soft coup. Before the election even happened, Trump announced his intent to do this, & began the conspiracy himself.

And yes, Republicans supporting this are doing it because of Georgia. They want to keep their power over the Senate, and Georgia is where the possibility is. If they blow Georgia up, they keep the Senate.

This is just to say that a coup looking like this is a thing that happens. This is a type of coup. No one is being hysterical when they say that. It's the correct word for someone laying down a conspiracy in order to illegally flip an election back to the losing party.

Some coups are violent, & others are stealthy. This one's a weird combo. It's not secretive - Trump started saying this was what he'd do months ago. He had no evidence of fraud then, of course. He never has. He's always said he wouldn't accept defeat. That's what this looks like.

In his - & other dictatorial - minds, defeat is impossible. There was never any version of a fair loss for him: to him, defeat itself is inherently unfair. He dropped mail vote fraud conspiracy groundwork, just in case, & built it up for months. It's always been for this purpose.

But call it by its name. What we're seeing is an attempt at a soft or silent coup. Just "coup" is appropriate too. I'll use it in a sentence: The Trump Administration, and much of the GOP are currently attempting a coup.

Note: coups etc. aren't my area of expertise. I'm a storytelling expert though (I've written a lot books, in a bunch of different genres) & the Trump administration is all storytelling. The storytelling re: mail-in voting has always been pointing at this set of plot points.
