FILE - In this Aug. 21, 2012 file photo, Republican vice presidential candidate, Rep. Paul Ryan, R-Wis., leaves a campaign rally in West Chester, Pa. This is the convention prelude of the Republicans' dreams _ their nightmares, that is. Mitt Romney wanted to preside over a made-for TV gathering showcasing his economic credentials and GOP unity. Instead, he's heading to Tampa with the national debate focused on rape and abortion and with the divisions within his party on full display. (AP Photo/Matt Rourke, File)
