BISMARCK-Sen. Tom Campbell, R-Grafton, announced Monday morning he would not seek his party's nomination in next year's race for governor.

Campbell, a farmer and businessman who was first elected to the North Dakota Senate in 2012, said "it probably wasn't the right time" for a run. He also cited the possibility he would be running against Attorney General Wayne Stenehjem.

"I just didn't want to split the Republican Party at this time," Campbell said following a press conference at a Bismarck hotel. He won re-election last year in District 19 with nearly 65 percent of the vote.

So far, only Republican Rep. Rick Becker of Bismarck has publicly announced he would run for governor. Gov. Jack Dalrymple announced earlier this year that he would not seek re-election in 2016.

Others in the mix are Stenehjem, Treasurer Kelly Schmidt and businessman Doug Burgum. On the Democratic side, former Agriculture Commissioner Sarah Vogel said earlier this month she was considering a run.
