What do you think?
They are comparing the early vote numbers in Nevada to 2014, which was the last midterm, but there was no Senate race that year, and the Governor race was won by Republican Brian Sandoval over Democrat Bod Goodman by 71% to 24%. Because of non-competitive races that year, it is not a good year for a valid comparison.
