WOODBRIDGE, Va. — The presidential campaigns were trying to win older voters Friday with speeches before the AARP and a new video produced by President Barack Obama's campaign that argued rival Mitt Romney derides seniors behind closed doors.

Republican vice presidential nominee Paul Ryan, who was bringing along his 78-year-old mother for an appearance before the AARP's convention in New Orleans, reassured attendees that he and Romney care about senior citizens.

"Mitt Romney and I share your concerns," Ryan said in remarks prepared for delivery provided by the campaign in advance. "And we respect you enough to level with you. We respect all the people of this country enough to talk about the clear choices we face on Medicare, Social Security, the economy, and the kind of country our children will inherit."
