Former Sheriff Richard Mack has announced that he will run for Congress as a Republican candidate in Texas’ 21st Congressional District. Mack is perhaps best known as a gun rights activist and as a speaker on the role of law enforcement in America. Mack was the Libertarian candidate for U.S. Senate in Arizona in 2006. He has also spoken at a number of events for the Constitution Party, including the North Carolina CP’s state convention in August. Mack has endorsed candidates from the LP and the CP in the past.

The district Mack is running in has been represented by Republican Lamar Smith since 1987.
