WASHINGTON--President Obama tapped his vast presidential campaign e-mail list to rally his troops behind his nomination of Sonia Sotomayor, sending a video to his backers and asking them to pass it on.

From Obama to his e-mail list, now managed by Organizing for America, housed in the Democratic National Committee...

"I am proud to announce my nominee for the next Justice of the United States Supreme Court: Judge Sonia Sotomayor.

This decision affects us all -- and so it must involve us all. I've recorded a special message to personally introduce Judge Sotomayor and explain why I'm so confident she will make an excellent Justice."
