North Dakota Democratic Sen. Heidi Heitkamp might be the most endangered Democratic senator in the nation this fall. President Trump won North Dakota by more than 35 points, and Heitkamp's opponent, Republican Rep. Kevin Cramer, has already been elected statewide as North Dakota's sole representative. Republicans have played up the economy and have tried to paint Heitkamp as too liberal for North Dakota, while Democrats have attacked Cramer on tariffs and health care.
