The droves of Sunni Arab residents casting ballots in towns like Falluja — the name itself synonymous with the cradle of the insurgency, where relatively few voted in the last election five years ago — promised to redraw Iraq’s political landscape. The turnout delivered Sunnis their most articulated voice yet on the national stage, seven years after the American-led invasion ended their dominance.  Yet the act of their empowerment Sunday may make that landscape even more combustible, possibly even risking a revival of sectarian conflict. The demands of Sunni voters, from securing the presidency for a Sunni to diluting Iran’s influence, could make the already formidable task in Iraq of forming a coalition government even more difficult.  At polling stations near cratered buildings, past blast walls that still bore the pockmarks of bullets, the sentiments of voters who largely boycotted Iraq’s national elections in 2005 illustrated that divide.  Even as many cast ballots for the slate of Ayad Allawi, a secular Shiite and former prime minister, they condemned religious Shiite parties. With the invective once reserved for Americans, voters now attacked Iran, seen here as the patron of Iraq’s Shiite-led government. – New York Times
