More than a thousand people packed into a chilly University of Pennsylvania quadrangle to hear first lady Michelle Obama tell young voters to support candidates who will help her husband advance his unfinished agenda.
Mrs. Obama told attendees at the Monday evening rally that digging out of the recession's depths is difficult. But she said "we have come too far" to stop advancing health care and educational opportunities.
She spoke just hours before Pennsylvanians pick a new U.S. senator and governor in Tuesday's election.
Democrats have a substantial registration advantage in moderate Pennsylvania, thanks in part to a surge two years ago in support of Barack Obama's presidential candidacy.
But Democrats are trying to get those voters into election booths to counter widespread discontent with joblessness and a strong Republican reaction to the Obama administration.
