The overriding issue of the next legislative session quietly starts its 10-month road show this week in Abilene with the first public hearings on redistricting. The House and Senate committees will collect opinions about what should and shouldn't be split geographically around the state, a record that will be used in the court battles that will almost certainly follow the next Legislature's final decisions on the state's political fence lines. Some members think that public testimony will be important in court. Some think it will be completely ignored once the pencils are put away in favor of ink pens.
