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.
