  • Widening of both the gender and marriage gaps in Democratic margin.
  • Growing regional divides between eastern and western North Dakota.
  • The oldest electorate since at least 2006.

Moreover, the median voter age across presidential elections (from 50 in 2008, to 52 in 2012, and then 53 in 2016) and midterms (from 52 in 2006, to 54 in 2010, to 55 in 2014, and then 56 in 2018) has steadily increased every election cycle from a low of 50 in 2008 to the current high of 56. As age is a good predictor of party preference, one wonders if this 12 year trend will contribute to more Republican electorate in the state’s future elections.
