Former U.S. Rep. Colin Allred has launched a campaign for the Senate seat held by Republican John Cornyn, pledging to be a voice for Texans wracked by higher costs of living and what he views as a “rigged” political system.

U.S. Air Force Col. Terry Virts, a former F-16 fighter pilot and NASA astronaut, is the other Democrat in the race.

Democrat Colin Allred is once again running for the U.S. Senate. The former congressman from Dallas announced his candidacy on Tuesday.
