CBS News anchor Katie Couric gathered Iowans from all over the state to find out what's really on their minds.
Among CBS News' questions, Couric asked: What do you think is the most important issue?
(Pat - registered republican) "Border control for the reason of national security," said Pat, a registered Republican.
"I think that the world is increasingly complex and dangerous," said Karen, a registered Democrat. "It seems to that the United States is hated or feared in much of the world, so I want a candidate that can change that."
"I would say that it's the war in Iraq and getting that resolved as quickly as possible," another Iowa resident said.
"Health insurance. I'm a small business owner and my premiums have gone up 20 percent a year," said Mark, a registered Republican.
David, a Democrat, said: "Fixing the social security mess and taking away tax credits for the rich."
"I'd probably have to go with immigration," said Debbie, a Republican. "Having so many illegal immigrants affect our education and the way our schools deal with it."
Couric asked the group: "Are you satisfied with the direction of the country?"
"At a macro level, I am satisfied with what we're doing. I think there are things of course that can always be changed," said 25-year-old Jordan, a registered Republican.
"I keep sitting here thinking politics as usual when not get us out of this horrible mess that we're in right now," said Sherman, a registered Democrat.
Mark, a registered Republican said: "This country does need change. We need a leader. We don't need a politician and I think that's the issue."
"I'm very unsatisfied and I'm very worried," said Mary, a registered Democrat. "I have grandchildren and the debt we're leaving them. I just think it's so unfair."
"I'm extremely dissatisfied," said registered Democrat Bobby. "And I think the biggest change we need is in foreign policy."

"How do you feel about your role in the process?" Couric asked.
Debbie, a Republican, said: "We educate ourselves about the role in the political process and I think, I myself am honored to be a part of this process."
And Republican David said: "I find it a little bizarre, frankly, that Iowans have so much power in this-in this matter because the state's population is not representative."
"It's nice not to get confused with Idaho and Ohio anymore," said Bill, a Republican.
