What the Governor of Texas Can Do About Congressional Maps

Every ten years, states redraw their political boundaries in a high-stakes process that can shape power for a decade. In Texas, the governor sits at the center of this storm. But what can they actually do about congressional maps? A lot, it turns out.

The Primary Power: The Veto Pen

First and foremost, the governor’s role in redistricting is the same as for most other legislation: they can sign the maps into law or veto them. In Texas, the state legislature has the initial responsibility for drawing the boundaries for its congressional districts. They pass a bill, just like any other, and send it to the governor's desk. If the governor signs the bill, the new maps become law, pending any court challenges. If the governor vetoes the maps, they are sent back to the legislature, which would need a two-thirds majority in both chambers to override the veto — a high bar in any political climate. This veto power is the governor’s most direct and potent tool, allowing them to reject a map they find politically unfavorable or legally

dubious.

The Nuclear Option: Calling a Special Session

What happens if the legislature can't agree on a map during its regular session, or if the governor's veto stands? For congressional maps, the governor holds another powerful card: the ability to call a special session. These sessions, which can last up to 30 days, force lawmakers back to Austin to focus only on the agenda set by the governor. This gives the governor immense leverage. They can use the threat of a special session to pressure lawmakers to pass a favorable map or call one to give them another bite at the apple. This exact scenario played out in 2021 and again in a highly unusual mid-decade redistricting effort in 2025, when the governor called lawmakers back to Austin to redraw congressional maps specifically to increase partisan advantage ahead of the 2026 elections.

The Backup Commission (But Not for Congress)

Texas has a unique backup system called the Legislative Redistricting Board (LRB). This five-member board, composed of the lieutenant governor, speaker of the House, attorney general, comptroller, and land commissioner, is constitutionally required to take over if the legislature fails to draw maps for its own state House and Senate seats. However, there’s a crucial catch: the LRB’s authority does not extend to congressional maps. If the legislature and governor can’t agree on a congressional plan, the responsibility falls to the courts to draw a map. This distinction is vital. While the LRB provides a political backstop for state legislative districts, the failure to pass congressional maps throws the process into the federal judiciary, a scenario all political parties usually try to avoid.

The Bully Pulpit and Political Pressure

Beyond formal powers, a Texas governor wields significant informal influence. By using the “bully pulpit,” a governor can publicly endorse or condemn certain proposals, shaping media coverage and public opinion. They can pressure their party members in the legislature to hold the line on a particular map and can be the state's chief defender of the maps in the court of public opinion. For example, during the 2025 mid-decade redistricting, Governor Greg Abbott publicly celebrated signing the new map, claiming it ensured “fairer representation.” This kind of political messaging is crucial in a process that is as much about narrative as it is about drawing lines on a map. A governor can set the tone, define the party’s goals, and rally support, making their influence felt long before a bill ever reaches their desk.
