If you had any doubt that young voters are making a major splash on this year's primary elections, check out Rock the Vote's latest tally of 18-29 year olds' primary turnout.

More than six million voters under 30 have cast ballots in the 2008 primaries and caucuses so far. A very conservative estimate is that this more than 2.2 million more than voted in the most recent comparable primaries!

Check it out - our updated 2008 primary turnout factsheet (PDF) lays it all out.

Young voters are leading what's become a major charge to the polls this year. More than 3.5 million new people registered to vote in the early months of 2008, or one in 65 American adults, and youth turnout has doubled and tripled in nearly every primary so far this year.

Here at Rock the Vote, since July 2007 more than 860,010 people have used our online system to register to vote, including 592,016 under-30 voters!
