North Dakota Senate candidate Heidi Heitkamp will skip the Democratic National Convention in Charlotte this September.
Heitkamp's spokesman Brandon Lorenz told Hotline On Call that the former state attorney general will be campaigning in North Dakota rather than attending the gathering.
Heitkamp is locked in a tight race with Republican Rep. Rick Berg. North Dakota has leaned increasingly Republican in the last few years, and President Obama is unpopular in the state. Heitkamp has distanced herself from the president, particularly on energy issues.
Heitkamp joins a growing list of Democratic Senate candidates opting out of Charlotte, including Arizona Senate candidate Richard Carmona, Sen. Claire McCaskill, D-Mo., Sen. Jon Tester, D-Mont., and Sen. Joe Manchin, D-W.Va.
