Rules the democrats put in place on themselves twice, and republicans remove as soon as they’re in power.

Nope, the republicans have not removed the filibuster or senatorial holds. (side note: In the past, the filibuster was restricted in regards to appointing justices/federal judges only. First by Dems for SCOTUS justices, then by Repubs for federal judges. Other than that neither of them have removed the filibuster. The filibuster and senatorial hold are the rules I was talking about, which are the main ways that repubs stymie Dems' ability to pass legislation (and the other way around BTW).

We saw it under Bush when he went to war without congressional approval and essentially said “Yeah I’ll ask permission to stay 9 months into the war”.

But he did get congressional approval beforehand when they passed this resolution. Of course he got it by lying to Congress and the UN .
