Just some quick calculations, but 85.8% of "voters" aged 90+ voted in this election, according to that data (if you remove the DM victims and 01/01/1900 cases). 81.3% of people aged 100+ voted.
Way higher than normal participation rate. For comparison, only 56% of the US population voted in the presidential race in 2016. Edit: That's giving them the benefit of the doubt that these people are even alive, including the pre-Civil War voters.
