The Texas GOP is at war with itself. The outcome could signal the national party’s future.

After more than two decades of dominating Democrats and ruling over all three branches of state government, the Republican Party of Texas has gone to war with itself.

Stark battle lines have been drawn between mainline Texas conservatives and a more far-right faction that has gained influence within the party in recent years — mirroring the ideological fractures that left Republicans in Washington unable for weeks to elect a new U.S. House speaker after they ousted Rep. Kevin McCarthy.

The Texas GOP’s civil war has been building for years, inflamed in part by an expansive network of ultra-conservative activist groups bankrolled by a trio of West Texas billionaires on a mission to push the deep-red state even further to the right.

After The Texas Tribune reported this month that some of the leaders of that influential far-right network met for hours with the white supremacist provocateur Nick Fuentes — who has praised Adolf Hitler and called for a “holy war” against Jews​​ — the intraparty tension reached a breaking point.

This week, Texas House Speaker Dade Phelan, a staunch conservative who’s nonetheless a target of far-right attacks, called on the state GOP to cut ties with any groups and individuals who have embraced white nationalist figures or rhetoric.
