An exclusive statewide poll by Valley News Live and Mason-Dixon Polling shows, that not even a week after North Dakota's primary, the race for the U.S. House will likely be decided by the undecided.

The statewide poll shows Kelly Armstrong holding a double digit lead over Mac Schneider, but an even larger percentage, who haven't made up their mind. Valley News Live commissioned the poll through Mason-Dixon Polling. 625 voters in North Dakota were interviewed by phone for the poll. There's a 4% margin of error.

When you look at the overall state, the Republican Armstrong stands at 46%, Schneider 35%, and 19% undecided. The Democrat Schneider has big support in Fargo and Cass County. He's at 52%, Armstrong 32% and undecided 16%.

But that's the only area he leads. In Eastern North Dakota, Armstrong is at 43%, Schneider 36% and 21% say they are not sure at this point. The numbers for Bismarck-Mandan reflect strong support for Armstrong, 53% to Schneider at 26%. Again, the undecided is substantial at 21%.

For Western North Dakota, not much change. Armstrong with 56%, Schneider 26%, undecided at 18%,

The poll was conducted just last week from June 13th through the 15th. Four key statewide races were also involved in the poll.

Right now, the numbers show strong support for incumbents.

In the race for Secretary of State, Al Jaeger, who did not win the Republican Party's endorsement and is now running as an independent, leads Democrat Josh Boshee. Jaeger 51%, Boshee 32%, Libertarian Roland Riemers 6%, undecided at 11%.

In the race for North Dakota Attorney General, Republican Wayne Stenehjem holds a comfortable lead over Democrat David Clarke Thompson, 64% to 27% with 9% undecided.

For North Dakota Agriculture Commissioner, incumbent Republican Doug Goering leads Democrat Jim Dotzenrod, 57% to 32% with 11% undecided.

In the race for Tax Commissioner, Ryan Rauschenberger stands at 52%, Democrat Kylie Oversen 34% with 14% undecided.
