Not surprising. Olds in MN are more Democratic than youngs + the general Democratic enthusiasm will ensure that the non-old vote is more Democratic than it would be otherwise. The former is a huge reason why Dems held on there in 2010/14 when cracking most everywhere else comparable.
Yep. It wasn't that long ago at all that states like TN and AR were more Democratic among olds than youngs, and even today, there's evidence to suggest that it holds true in states like MO: Kerry won the 65+ vote in all three of those states (while ironically losing in MN, as well as WA, OR, VT & NY)!
(FWIW IL is an error on that map; should be Democratic)
As late as 2004 there were still elderly people who remembered the New Deal making their lives better, and they could never vote Republican.
