There has to be some consideration that not all the Republicans are on the same side. If you treat them as a unified group, you cannot separate them into groups of "good for this reason, bad for that reason"; and you lose the ability to help some Republicans fight against other Republicans.
This applies to the Democrats as well, because there are plenty of rotten apples in that barrel.
I've given that consideration for over 10 years now. The last straw was Trump's entire presidency. All the shit that's happened and they refuse to do anything about it. They couldn't even vote to kick the Qanon loving, Jewish space laser conspiracy spreading senator from her duties. Republicans fall in line every time. The only discourse is in the democrats, because it's made up of everyone left of bat-shit crazy right.
Yeah, I agree with this. The "fall-in-line or be ousted" mantra has been a successful approach for the ass-hats that currently call themselves Republicans. Every Republican that dissented gets branded a traitor by other Republicans, and I still hope Liz Cheney will survive the churn.
I associate this problem with the election system, where an independent candidate can take votes from another candidate. It leads to that "fall in line with the group or be punished" attitude.
I am hoping rank-choice voting gets more usage, because it clearly would allow the majority to say "anyone but that guy" but still allow "that guy" to get brought in at the local or state level where their politics do have a majority backing. This seems fundamentally correct for "representation".
