BAGHDAD, Iraq (CNN) -- Voting in Iraqi provincial elections ended peacefully Saturday evening, and the mood was festive in some places, unlike the violence, intimidation and apathy that marked the balloting in 2005.



An Iraqi casts his vote Saturday in Ramadi. Preliminary results are expected in a week.



"There is a new norm of politics. ... It is truly a proud moment," Iraqi Deputy Prime Minister Barham Saleh told CNN. "The distance that we have come is truly inspiring."



Faraj al-Haidari, who chairs the Independent High Electoral Commission of Iraq, and Staffan de Mistura, special U.N. representative for Iraq, issued statements saying the election went smoothly.



"Hundreds of thousands of IHEC staff worked dutifully according to procedures," said Mistura, who also said he was pleased at the number of women who turned out to vote.



Preliminary results from the electoral commission are expected within five days, de Mistura said. Final numbers are due at the end of February.



"Some security incidents were reported during the day, but we didn't have any confirmation on serious security incidents that might effect the total electoral process," al-Haidari said.



President Obama congratulated the Iraqis on the elections.



"Millions of Iraqi citizens from every ethnic and religious group went peacefully to the polls across the country to choose new provincial councils," Obama said in a statement released by the White House. "It is important that the councils get seated, select new governors and begin work on behalf of the Iraqi people who elected them."



He said the United States "is proud to have provided technical assistance, along with the United Nations and other international organizations, to Iraq's Independent High Electoral Commission, which performed professionally under difficult circumstances."



CNN's Arwa Damon, who toured polling stations with UN observers, said she noticed an increased sense of awareness and optimism among voters, who felt that their participation would have an impact on their lives and country.  Watch Iraqis head to polls »



Political analysts said this election could correct some of the political imbalances that resulted from the 2005 election. Saturday's voting also was seen as a referendum on Prime Minister Nuri al-Maliki.



"We are trying to build a new system of government in the heart of the Islamic Middle East," Saleh said.



The last provincial elections were in January 2005, after the ousting of Saddam Hussein, and most Sunnis did not vote.



"This time, happening four years after the first elections, means that this process is on track to building a functioning democracy," Saleh said. "I think the election results will point to the real political map of Iraq.



"The overwhelming majority of the people of Iraq are having a stake in this process, are buying into this democratic process."



He added that politics "is no longer defined by violence" and is now transcending "sectarian and ethnic dimensions."



Voting was extended by one hour, partly because a curfew had been lifted, allowing more Iraqis to go to the polls, said Judge Qassim al-Aboudi, a member of the Electoral Commission. He described turnout as "good."



Those elected will have regional power over the essentials Iraqis have been desperate for: basic services and jobs, Damon reported.



She said there was a sense of jubilation in Anbar province, the Sunni heartland west of Baghdad. The sprawling desert area was dominated largely by al Qaeda in January 2005, when the first provincial elections after the fall of Hussein were held.



In 2005, fearing retribution from the terrorist group, only about 2 percent of eligible voters cast ballots.



In Najaf, the Shiite center south of Baghdad, voters also were eager to let their voices be heard, Damon said.  Watch Arwa Damon on the importance of these elections »
