North Carolina citizens voted in the 2012 primary last night, but some races did not yield a true winner. According to state law, if no candidate receives 40% of the vote in a primary, a second primary (or runoff) election is needed.

Over 10 races, including republican races for Lieutenant Governor and three U.S. House seats, will be headed to a runoff election.

Thanks to a new law passed by the North Carolina General Assembly last year, the primary will be held 10 weeks following the first primary, rather than the usual seven weeks. The new law took effect, because at least one of the races headed to a runoff was a U.S. Congress seat.

The runoff election will take place on July 17, 2012.
