A coalition of mostly Hispanic members of the Texas House are filing suit to try to stop the use of new statewide voting maps. The Mexican American Legislative Caucus is accusing the Republican-led Texas Legislature of ignoring part of the state constitution. The state’s “county line rule” requires lawmakers to keep county boundaries in mind when creating House districts. The focus is on Cameron County, where two House districts were fully contained inside the county for the last ten years. The newly drawn maps have only one House district fully inside the county’s boundaries. Several groups have accused state lawmakers of drawing district boundaries to dilute the voting power of minorities in certain areas of Texas.
