More than 125 million Americans -- 64 percent of those ages 18 and older -- went to the polls in last year's presidential election, according to data scheduled to be released today by the Census Bureau.
That's the highest it's been for a long time; since at least 1924 according to this graph from [link|http://www.fairvote.org/turnout/preturn.htm|here]:

There may be differences in the methodology, and people between 18 and 21 only have been able to vote in presidential elections since 1972 (26th Amendment).
Cheers,
Scott.
