Interesting article on the demographic breakdown for the 2018 midterms based on a poll of 90,000 people. There's a lot of blue in these charts which looks good for the Democrats...until you look at share of the vote for each group. The country is getting older and the future appears to hinge on how women 38 or older and especially 45 or older will vote in the future.
