In a biennial ritual, my CIRCLE colleagues and I will be working most of the night to calculate the youth turnout from the 2012 election. At this moment, the National Exit Polls are reporting that youth represented 19% of the electorate. That is a promising sign. The youth share of the vote is up a point compared to 18%, and it’s not a bad showing by any standard, since 18-29s represent 21% of the adult population, so they are punching at close to their weight. However, share does not equal turnout, as our handy graphic reveals. Stay tuned tomorrow for our actual turnout estimate, at www.civicyouth.org.
