Seniors get out and vote.
Last election here was just local: city council, school board, forest preserve commissioners. Oh, and the school bond referendum. (which would have raised property taxes.) Turnout was 10-12% in most precincts.
The polling place I worked had two precincts, one with a large retiree community, total turnout between the two -38%. It probably would have been more, but the polling location wasn't within walking distance and it was rainy that day.
Yeah, the bond referendum lost 63% to 37%
