In a conference call with reporters today, Romney senior adviser Ed Gillespie said that  voters faced a “choice between a  dynamic growth economy that fosters upward mobility or a stagnant economy that fosters government dependence.”

“We believe,” Gillespie continued, “that as we head into the debate season and Americans will begin looking and seeing these two candidates side by side for the first time, we think that this emphasis on the stark choice will be critical to how they decide to vote in November.”
