The Biggest Voting Bloc

Wilkinson measures the political power of seniors:

[T]hat nearly a third of the voting public is 65 or older does not quite capture the overwhelming electoral heft of seniors. Retirees are disproportionately likely to actually show up at the polls. Moreover, the interests of seniors are more unified than those of younger voters whose electoral might is divided between often competing and offsetting interest groups. The votes of small business owners and school teachers tend to cancel each other out, but America's silver foxes constitute a more or less consolidated force fighting for the protection of old-age entitlements.
