The four states with the highest turnout (MA, NH, MN, CO), figure prominently in my own family history. Probably has something to do, with me becoming a political junkie from the Nixon-JFK contests, and thereafter.
(Certainly nothing to be proud of, but I was that HS kid who in Nov. 1963 clapped when Kennedy's death was announced over the intercom. It wasn't fatal for me however, since it was a fairly widespread sentiment in historically ultra-conservative OC, CA)
I was punished for my bad behavior by having to watch non-stop B&W TV coverage of all things JFK, for the next few days. I just wanted to go surfing.
