I kinda hope we see Texas move forward with this effort, because I think the Republicans will fuck it up and not gain the 5 seats as promised. Trump won't be on the ballot in 26, and lots of independents don't like this version of him. I think the Rs may be putting other seats in jeopardy that they assume are safe, and this could lead to a some upheaval in the state reps currently in power. It wouldn't be the worst thing if that happened even if the numbers slightly change.
More importantly, this nakedly obvious illegal and unethical power grab will give several blue states the motivation and reason to do the same, in a way that will be a huge net positive for the Dems seats in Congress. They have to fight fire with fire, and if they actually believe their warnings of "losing democracy forever" are true, then they need to occupy every seat possible to prevent it. California can definitely squeeze a few Rs out of power, Illinois, Maryland, Michigan, etc could all pick up a few more seats. If they all do it, it would result in a seismic shift that could prevent the House from turning red for another decade.
The only reason Mike Johnson is even in power is because so many red and purple states have already done what Texas is threatening. So fuck them, fuck playing fair and doing the right thing, moral victories are for losers. Go win the damn thing and start blocking the dumb shit this administration spews out. Fight dirty, fight clean, whatever it takes, just actually fucking fight it.
