The last Democrat elected to the Senate seat Cristina Tzintzun has her sights on was Lyndon Johnson.  Republican takeovers are just a fact of life in the South.  And yet in some places, there's light at the end of the tunnel for beleaguered Dems.  It's in the Lone Star State that they hope to reverse the trend.  Texas is urbanizing, and it's getting more educated and more diverse.  Tzintzun -- a political organizer who's the daughter of a Mexican immigrant and an Anglo-Texan -- tells Alec that by activating those Democratic base constituencies, she can win where others have failed.  It's a trail begun by Beto O’Rourke, who almost won the state’s other Senate seat back for the Democrats in 2018, but it's a perilous strategy, too, in a state as conservative as Texas.  Much of Beto's team has come over to help Tzintzun, and full disclosure: Alec, too, is a supporter, and hosted a fundraiser for her in October.
