This should be identified as a Democratic pollster.
FARGO - There is precedent for a Republican U.S. Senate candidate in North Dakota being given a 10-point polling lead over Democrat Heidi Heitkamp. It didn't end well for the Republican.
Democrats are hoping history repeats itself, as a poll commissioned by NBC North Dakota shows Republican Kevin Cramer leading the incumbent Heitkamp 51 percent to 41 percent, with 8 percent undecided. [...]
There is one voice that, perhaps, to which we should listen a little more closely.
It is that of DFM Research out of the Twin Cities, a political polling firm owned by Dean Mitchell, who almost immediately took to Twitter after the latest poll to offer his own numbers that softly questioned the veracity of NBC North Dakota's poll. DFM later released a memo to the North Dakota Democratic-NPL party that was turned into a press release. [...]
