Mitt Romney once again pitches himself as the presidential candidate best poised to effectively reform government, in a new ad set to run in Iowa. The 30-second spot, which features footage from a speech by the former Massachusetts governor, will run in the Hawkeye State ahead of the first-in-the-nation Jan. 3 caucuses. "I'm going to do something to government. I'm going to make it simpler and smaller and smarter, getting rid of programs, turning programs back to states, and finally making government itself more efficient," Romney says in the commercial, titled "Conservative Agenda."
