Clinton campaign:

"Congratulations to Senator Obama and his campaign on their victory tonight. It's been a hard fought race here in Iowa for the last year and all eyes now turn to New Hampshire.

Hillary is going to continue making the case that in these serious times when America faces big challenges, it will take a leader with the strength and experience to deliver real change.

This race begins tonight and ends when Democrats throughout America have their say. Our campaign was built for a marathon and we have the resources to run a national race in the weeks ahead."

John McCain:

"I thank each and every Iowan who braved the cold to caucus tonight, as well as my tremendous Iowa staff and leadership for all of their hard work over the past year. They worked wonders with far fewer resources than their competitors. I also congratulate Governor Huckabee on his victory tonight.

"Now the campaign turns to New Hampshire for the first-in-the-nation primary. As Granite State voters know best, I will continue to deliver straight talk about the critical issues facing our country. I will talk about the unique experience that prepares me to lead as commander in chief from day one, and makes me the only Republican who can win the White House in 2008.

"We started this together, New Hampshire, eight years ago. In five days, we're going to send the same message we did then: change is coming."

Giuliani Campaign:

"We congratulate Mike Huckabee on a hard-fought victory in Iowa. This race is wide open and we will continue to run a national primary campaign designed to win the number of delegates necessary to become the Republican nominee. Rudy is the only Republican candidate who can not only win the primary and general elections, but will turn purple states red."

Bill Richardson:

"We made it to the final four. My staff and volunteers worked their hearts out to get us here. Now we are going to take the fight to New Hampshire.

"It has been an honor to meet with Iowans and be a part of this extraordinary process. I am the one candidate who has said we must end this war by getting all our troops out of Iraq. We cannot truly change this country until we end this war -- and we can only do that by getting every US troop out. Americans who want to get us out of Iraq aren't giving up and neither am I. We cannot end the division in this country until we are out of Iraq and we cannot focus on fixing our problems at home and our image abroad until our troops are out of Iraq. We cannot wait until 2013 or longer.

"Thank you, Iowa. Now we go on to New Hampshire."
