In what’s shaping up to be a historic election for Dallas County, former state District Judge John Creuzot announced his Democratic candidacy for district attorney — an election in which all of the announced candidates are African-American.

Surrounded by a group of community leaders, pastors and former U.S. Trade Representative Ron Kirk, who served as Dallas’ first black mayor, Creuzot said that his 22 years as a criminal court judge makes him the best candidate for the job.
