Declare Yourself, a national non-partisan, non-profit youth voter initiative founded by producer Norman Lear, has attracted some big names to its advisory board. Tyra Banks, producer/director J.J. Abrams, NBC co-chairman Ben Silverman and ESPN's Stuart Scott are among those who will help steer the get-out-the-vote effort between now and the presidential election. Friends of the organization include Jessica Alba, Scarlett Johansson, Hilary Duff, Adrian Grenier, Mandy Moore and Kate Walsh.
