The scene in Brian Griffin's bedroom looks like a cross between a charity telethon and an intense cramming session the night before a final exam. Mr. Griffin and about 10 of his classmates--fellow members of the Plainfield High School (Indiana) chapter of Students for Barack Obama--are sprawled around the room, cellphones in hand, studying voter databases on their laptops. They are trying to locate Indiana supporters of the U.S. senator from Illinois and urge them to turn out for the upcoming primary--or better yet, they hope, to volunteer for the campaign. No matter which candidate young people are working for and why, becoming active in campaigns and other civic activities as early as high school may translate into greater political involvement on their part later in life, said John Roos, a political science professor at the University of Notre Dame. Roos also states that volunteering helps students learn how their actions can affect the political process.
