WASHINGTON – Rick Perry's explosive comments and past writings about Social Security have delighted Mitt Romney supporters and some advisers, who see the Texas governor as having made himself more vulnerable in one very crucial early Republican presidential primary state: Florida.Some in the Romney camp believe that Perry's recent remark that Social Security is a "ponzi scheme" and a "monstrous lie" will cost him support among seniors in the retiree-heavy Sunshine State, which is very likely to determine the primary winner.
