They nailed the presidential election results in Virginia in 2016.
For reference, their final poll was 48 Clinton, 42 Trump, 3 Johnson, <1 Stein, 2 McMullin.
Their final projected result (spiting/pushing undecideds) was 50 Clinton, 44 Trump, 3 Johnson, 1 Stein, 2 McMullin. This is scarily accurate, with the only real misstep being McMullin and Trump splitting a percent rather then McMullin have 2.
Doing the same to the above results yeilds:
Northam 52%, Gillespie 46%, Hyra 2%
Fairfax 52%, Vogel 48%
Herring 52%, Adams 48%
