The biggest reason the public resists reform regarding partisan elections in Texas is likely because they wish to keep judges accountable to the voters.
What would Texans prefer
Texans might prefer to maintain the system of electing judges through partisan elections as it allows them to have a direct say in selecting judges and holding them accountable based on their performance.
This desire to keep judges accountable to the voters could be a significant factor in the resistance towards reforming the current system of partisan elections for judges in Texas.
