From Texas Standard:
Other than, perhaps, Beto O'Rourke, few politicians have generated quite as much interest or excitement lately among Democrats as freshman House member Alexandria Ocasio-Cortez. She already generated political buzz after her stunning upset over 10-term incumbent Joseph Crowley. Now, a group that backed the unabashedly progressive Ocasio-Cortez hopes to pull off a similar upset in the Lone Star State. The political committee, which calls itself Justice Democrats, now has its sights set on toppling Democrat and veteran South Texas Congressman Henry Cuellar.
Dave Weigel, national political correspondent for The Washington Post, says Justice Democrats is very closely aligned with Ocasio-Cortez. The group began as a post-2016 supporter of Vermont Sen. Bernie Sanders. They worked to elect first-time Democrats on platforms that resembled those of Sanders – Medicare for All, a $15 minimum wage.
