The intensity of the race for the White House was seen across Iowa this weekend as candidates zipped around the state by bus, plane, van and car — hoping to lock in supporters who’ll turn out on Caucus Night. Each of the three Democrats locked in a tight battle here began their Sundays with interviews on nationally broadcast television shows, then fanned out across the state.

John Edwards made stops in five Iowa cities on Sunday. "Iowa Caucus-goers are looking for someone who will fight for them, who will stand up to the corporate greed that’s killing health care reform and energy transformation and a tax and trade policy that works for Americans," Edwards said during a telephone interview with Radio Iowa. "That’s what I will do. I will fight for them with everything I’ve got."

Barack Obama made stops in four Iowa cities on Sunday. "Just great crowds. Tons of people who are first-time Caucus-goers as well as previous Caucus-goers. The energy in the room is great. Our organization looks great on the ground," Obama said during an interview with Radio Iowa. "So, you know this is going to be a very close election but if we go into caucus with the same enthusiasm and energy we’re seeing out here then we think we’re going to do really well."

Hillary Clinton made four campaign appearances in Iowa on Sunday. "We want to talk about the positive changes I have brought in people’s lives and the ones that I will bring as president," Clinton said during an interview with Radio Iowa. "We want to run a campaign that really reaches to as many people as possible, answers their questions, provides them the support they need to make this important decision."

On the Republican side of the equation, polls show the race between Mitt Romney and Mike Huckabee to be too close to call.

Romney visited five Iowa cities Sunday. "I think it was very important for me very early on to make the decision to be fully engaged in the Iowa process…to win the White House, our nominee has to be able to win in Iowa and if the nominee of our party has just not put in the effort to try to win in Iowa, then the likelihood of being able to win in the fall against a Democrat is not very high," Romney said during an interview with Radio Iowa.

Mike Huckabee spoke with reporters after emerging from a church service Sunday morning in Des Moines. "I prayed for strength for the weak," Huckabee said. No one asked for clarification, so Huckabee could have been praying for strength for the days ahead — the week, instead of strength for the weak of heart, mind, body and soul.

The sermon Huckabee and his wife heard was about running the race. "It’s a lot like our church at home in Little Rock," Huckabee said, "so it felt very much at home."

Huckabee was a Baptist minister before entering politics.
