Hillary Rodham Clinton stood on another stage, facing another overflowing ballroom.

This time the locale was the University of Southern California, where the elegant Town and Gown hall was jammed to capacity Saturday morning with more than 400 members of the country's Latino political and business elite. The agenda: honoring the former secretary of state for her role in inspiring the creation of the Mexican American Leadership Initiative, a group of prominent Latinos who support philanthropic projects in Mexico and promote what Clinton called "a shared future" between the two nations.

But many of those in attendance had another mission as well: demonstrating the commitment of their support — financial and otherwise — if Clinton decides to make another run for the White House.
