I know they're exit polls so they should be taken with a grain of salt, but I couldn't believe just how well Trump did with young voters in Missouri.
-18-29 year olds: Trump won 51-40 (by comparison he only won 30-44 year olds: 48-44).
-18-24 year olds: 57-35 !!!
Cnn exit poll.
The Senate numbers actually kind of track the trends seen from 2004-2012, where young voters consistently broke pretty heavily Democratic. They clearly carried that towards Democrats other than Hillary. I actually hadn't thought to check the EPs in MO for Kander. Yet another annoying statistic showing that had Hillary done as well as Obama among youth in MO, Kander might have pulled it off.
However, if the youngest voters don't go back to at least some sort of majority-Democrat, then I can only think that the future of Missouri might be more Democrat-friendly but ultimately not really what I imagine qualifies as an emerging Democratic state. It takes more than ~15 years worth of heavily Democratic voters to shift the political landscape in a state like Missouri.
