Except that we don't usually turn out in number that are in the double digits so that's why we are ignored.
In 2008, 51% of voters 18-29 voted in the Presidential election.
In midterms in 2006 and 2010 we were in the 20-25% range.
When we are motivated and think it's an important election, we show up.
But even with bad attendance we represent 1/10 US voters and our numbers keep growing.
