Two Republican U.S. House members from central North Carolina are fighting for their political lives competing for the same seat. Tuesday’s primary in the 2nd District between Republicans Renee Ellmers of Dunn and George Holding of Raleigh marks the first time two sitting members of Congress have run against each other since 2012. Cary obstetrician Greg Brannon is also in the race.

The primary is occurring after federal judges in February struck down two districts as illegal racial gerrymanders. The state legislature redrew parts of all 13 districts in the state and delayed the March primary. Holding was drawn out of his current 13th District and decided to run against Ellmers in the 2nd District.

Voters overall are choosing nominees in 11 districts Tuesday. Turnout is expected to be extremely low.
