The Bush Line is just a reminder of who didn't finish the job the first time.

"The Bush Line" doesn't matter because Trump happened. There was no spine grown by Senate Republicans in the aftermath of 2006 and 2008. Were they humbled? Sure. But they had spent the better part of that decade gerrymandering their own party into a radical white identity party during that time in the wilderness, insulating themselves from having to change anything about themselves.

What changed from W to Trump? Certainly it wasn't the corruption, mismanagement, and lawlessness that made W's version of the Republican party lose elections at the end. Those things just intensified and they did it because a governing majority of the party cared less about accomplishing anything of value and more so about a naked and corrupt thirst for power.

"The Bush Line" is fine if you want to talk with national pundits, but it doesn't mean anything to the rest of us. It's fine for content, but that's about it.
