DES MOINES, Iowa (AP) — Trailing in a new Iowa poll, Republican Rick Perry says in a new ad running in the state that his jobs record is more important than on-camera polish.The Texas governor is trying to convert criticism of his performances during recent debates into an asset by arguing that President Barack Obama — and implicitly his chief GOP rival Mitt Romney — are better speakers than leaders.Perry says: "If you're looking for a slick politician, or a guy with great teleprompter skills, we already have that, and he's destroying our economy. I'm a doer not a talker."Perry had support from 7 percent of likely Iowa GOP caucus-goers in a poll published Sunday by The Des Moines Register.Perry, with an aggressive Iowa strategy, is expected back twice this week.
