This is why Democrats need to compete EVERYWHERE.
We won’t win every race, but it’s stupid and irresponsible to simply forfeit certain races to incumbents. Always but especially now, we need competitive elections. And at the bare minimum, make them spend money defending seats they had won by 17 pts

JUST IN: Democrats flip a red seat in the Texas Senate.
Taylor Rehmet wins against Leigh Wambsganss, a conservative activist who helped lead right-wing efforts to take over TX school boards.
With all early vote, and 95% of precincts, in, Dem up 57/43.
Trump won this seat by 17% in Tarrant County.

The governor of Texas is rapidly turning world-class universities into minor regional ones. Example:
Greg Abbott halts H-1B visas at Texas universities, agencies
The governor said public universities and state agencies may not seek new visas without permission through the end of the 2027 legislative session.

1. The thing about science that these jokers don't understand is that science cannot be vibe-coded.
Whatever its flaws, the point with vibe coding is that you're trying to quickly make something that sorta works, where you can immediately sorta see if it sorta works and then sorta use it.

That the loss of trust was among Republicans could have been partly due to scientists seeming disrespectful to Republicans, eg. a Fauci & Rogan interaction led Hotez to say "If we fail to embrace our conservative brothers and sisters, and treat them with dignity and respect, we lose as a nation".
