Taking the results of a single election (which as usual you fail to provide a citation link for) -- do not mean very much in a swing state where well over 40% voters of all ages do not strictly stick with party lines in the elections. What happened in one election can easily be reversed in the next.
So you have basically failed to look at more than one election result in North Carolina. The 2018 election means very little in the North Carolina perspective for 2020. The Democrats needs to put up a decent presidential candidate for 2020 or North Carolina will vote for Trump again as they did in 2016.
So what is your point.... Obviously the information you are pushing is not for North Carolina in 2016 where Trump won the popular vote and thus the EC votes.
Vanzants original post was about all voters not just NC.2020 turnout from the 35 and under crowd is likely to be higher than 2016.
The dynamics only matter in swing states --- it means very little in solidly blue/red states (as I outlined earlier). Each swing state needs to be analyzed individually to determine the size/impact/leanings of the under-35 crowd -- which will also greatly be impact by who the Democrats select as a candidate and the top issues they push. "Identity Politics" is a fail; actual issues such as medical coverage and college loans will have much better traction with the under-35 crowd in swing states.
Democrats won the Senate races in Pennsylvania,Wisconsin,Michigan,Nevada,Virginia ,Minnesota ,Arizona and Ohio in 2018. Democrats did better in FL, GA and Texas in 2018 than they did in 2016.With the increased presidential race turnout and felons voting in FL they probably win one or more of those states.
