It's common political chatter by now that there's no real path to controlling the country without taking Texas.
Democrats know this, and have been pouring increasing amounts of national resources into taking the Lone Star State, which hasn't seen a Democratic statewide official in what is going into a fourth decade.
U.S. Senate and gubernatorial races have tended to become hopeful battlegrounds, with Dems lining up every two years behind a rising star such as Beto O'Rourke as a seemingly solo standard-bearer. In 2020, O'Rourke as a contender for Governor brought in 1,869,419 Democrat Primary voters as compated to 1,934,047 Republican Primary voters. That's about as close as it has been in recent memory.
