“...the impotence of the GOP.”
Is impotent what you call the bad guy that loses a pro wrestling match?
I’m not sure I understand the nature of your question.
If you are implying that American politics, and primarily the two party system, is akin to pro-wrestling, which is staged and fake, then I would agree with that implication, and I would more accurately refer to the GOP as “complicit” under such.
But in general appearances, the GOP comes across as impotent against their “alleged” opponents, the democrats.
