Sixth-district congresswoman and presidential candidate Michele Bachmann is more than half way through her 99-county tour of Iowa in advance of the Jan. 3 nominating contest.

“Iowa is a word-of-mouth state,” she told a radio reporter. “It’s a very personal, person-to-person state and I think the very best way to campaign is positively, on the ground, going from city to city, meeting as many people as we can.”

Wednesday afternoon, during a stop in Henry County, she spoke about gun rights and said that the AR15—a civilian version of the M16 assault rifle—is her favorite firearm.

“I learned how to hunt here in Iowa from my dad. I went to gun safety when I was 12 and I  helped Minnesota pass a conceal to carry law,” Bachmann said. “I have a conceal to carry permit myself.”

At every stop on her tour, she’s been making a short video geographically tailored to the community she’s in.

Bachmann is polling near the bottom of the candidates, receiving a 7 to 10 percent share of the vote in Iowa.

CNN’s Brian Todd criticized Bachmann for calling North Korea  “the Wal-Mart of missile delivery systems.”

“When you compare that regime to an all-American brand that employs hundreds of thousands of people in the heartland, you might have a political problem,” Todd said.
