As of August 2025, there are approximately 8,133,683 registered Democrats in Texas, making up about 46.52% of the total registered voters in the state. The total registered voter population in Texas is about 17,485,702 people.

This means that although voters do not officially register as Democrats or Republicans, their party affiliation is recorded based on their voting behavior in primaries and other indicators.
