From barackobama.com via The Huffington Post:

On May 10th, Barack Obama is launching Vote for Change, an unprecedented 50-state voter registration and mobilization drive. More than 100 events will be held across the country that day. Obama volunteers will register new voters as the start of a six-month voter registration drive.

This looks to be an unprecedented effort to buck conventional wisdom about who votes, using technology and grassroots organizing to generate enormous turnout. It if it successful, the political playing field may be altered in ways that would greatly enhance the future fortunes of progressive politicians.
