The Missouri Corn Growers Association has endorsed Gov. Jay Nixon's re-election campaign.
The group says this is the first time it has made a gubernatorial endorsement.
Association President Billy Thiel says the group decided to endorse Nixon because he has promoted Missouri agriculture by helping to expand its markets globally. The group also cited Nixon's support for ethanol cooperatives, among other things.
Nixon, a Democrat, faces no serious opposition in the Aug. 7 primary. Four Republicans are competing to challenge him.
Earlier this summer, Nixon was endorsed by the political action committee for the Missouri Soybean Association. That group said it was the first time it had backed a Democrat for governor.
