North Dakota Democrats hope to take back congressional seats from GOP. Here's what to expect on Tuesday.

The North Dakota race for the open U.S. House seat is between incumbent Kelly Armstrong and Cara Mund. All three congressional seats in the state are currently held by the GOP.

Another citizen-led initiative also will put the question of marijuana legalization before voters, who rejected the idea four years ago.

The initiative would allow people 21 and older to legally use marijuana at home as well as possess and cultivate restricted amounts of cannabis. The state could register up to seven marijuana manufacturing businesses and 18 dispensaries.
