Vice President Joe Biden says President Obama "hit a home run" by nominating Sonia Sotomayor for the Supreme Court. In an e-mail to supporters, Biden lauds Sotomayor's legal and personal experience and asks supporters to get engaged -- and of course donate -- by going to Organizing For America's Web site.

"Please join me in becoming a part of this historic moment for the Court and our country," Biden writes in the e-mail. "Add your name now to publicly show that you, too, 'Stand with Sotomayor.' In these crucial early hours, let us leave no doubt about the people's support for this extraordinary nominee."

The vice president's team, including Chief of Staff Ron Klain and counsel Cynthia Hogan, has been instrumental in the nomination process and will continue to be leading up to and through the confirmation hearings. Even though he was standing next to Obama and Sotomayor at the announcement on Tuesday, Biden hasn't spoken out on his own regarding the nomination -- until his e-mail.

This is an early sign that the administration plans to rally its online base leading up to the confirmation hearings. Obama introduced Sotomayor to Organizing For America supporters on Tuesday. But, relatively speaking, the White House was slow in taking this fight online. Interest groups were prepping a few weeks ago, Democratic lawmakers jumped all over the announcement via Twitter, and other groups wasted no time launching ads either praising or attacking Sotomayor.
