Democrats are already using the news of President Obama's endorsement of same-sex marriage as a method to rally supporters to their cause.
As Nancy Pelosi emails, on behalf of the DCCC:
Isn't it great? President Obama just announced that he supports marriage equality for all Americans.
He joins many of us who have long-supported marriage equality because of what it tells our country -- and the entire world -- that all of America’s families deserve the benefits of equal protection under the law.
