In general, the rural areas are red and the cities are blue. Austin, Dallas - Fort Worth, Houston, San Antonio, all center to left leaning. Literally everywhere else is full of repuglicunts or ‘libertarians’.
A greater number of people in the state lean left rather than right, but a greater number of districts lean right rather than left. This is primarily because there are far more rural areas in the state than otherwise, but gerrymandered districts make the problem worse.
