KERA/North Texas Public Broadcasting in Dallas is being sued by four Democratic candidates for Texas governor for not being included in a televised debate, reports the ValleyCentral.com news site. The candidates, Star Locke, Alma Aguando, Felix Alvarado and Clement Glenn, filed the lawsuit Tuesday asking for $400 million. They allege racial discrimination for being Native American, Hispanic or African-American. KERA released a statement Wednesday: "We are disappointed that these candidates have chosen to ignore years of judicial precedents upholding our right to use viewpoint neutral criteria in selecting candidates to participate in the Texas Debates. We are confident in our debate policy, and we will seek the speedy dismissal of this complaint as we have successfully with others in the past."
