Rep. Andre Carson easily defeated three Democratic challengers in Tuesday's congressional primary to win his party's nomination in central Indiana's 7th District.

Carson will face Carlos May in November. May is a former aide to Indianapolis Mayor Greg Ballard who lost in the primary two years ago.

If Carson wins a third term in the seat once held by this late grandmother, Julia Carson, he would become Indiana's second-longest serving congressman because of recent turnover in the delegation.

Carson drew criticism last year when he used a lynching metaphor to describe tea party policies, saying they would turn minorities into "second class citizens." Carson later said he wished he had used a different analogy but would not have changed the substance of what he said.
