National exit polling shows 18 percent of today's voters were aged 18-29. While that 's up sharply from this age group's 12 percent turnout for the 2006 election, its exactly the same as the percentage of 18-29 year olds as in the 2004 and 2000 presidential elections.
Seventeen percent of the voters in 1996 were 18-29 year olds and in 1992, the number was 21 percent. That means, if today's trend holds, candidate Bill Clinton will have turned-out a larger percentage of young voters in 1992 than Barack Obama did this year. In Ronald Reagan's re-election year of 1984, 24 percent of the voters were 18-29. When Jimmy Carter was elected in 1976, a full 29 percent of the voters were 18-29.
Among this year's 18-29 year olds, exit polling shows 66 percent voted for Obama and 31 percent for McCain
