Both Hillary and Obama have been courting the youth vote in South Carolina. Here's the numbers:

The stakes are high for the candidate who can mobilize the 612,000 eligible South Carolina voters younger than 29.

Last Saturday's GOP primary drew 44,000 young voters, according to exit polls. That was only 10 percent of the total turnout of 443,000. In contrast, 35 percent of the Republican voters last Saturday were over age 60. That trend relegated Mike Huckabee, who blitzed college campuses last week, to second place behind John McCain, who won with older voters.

According to the Secretary of State, there are 2,246,242 registered voters in South Carolina in 2,048 precincts. In the 18 to 24 age group, there are 216,877 voters -- in the 25 to 45 age group, there are 738,704 voters. These numbers include Democrats, Republicans and Independents.

So, there are almost a million voters under age 45. By contrast, there are more than 1.5 million registered voters over age 45.

In the 2004 presidential primary, 184,288 voted in the Democratic primary.
