With a hero who gave his life for the elections, a revived national anthem blaring from car stereos and a greater willingness to help police, the public mood appears to be moving more clearly against the insurgency in Iraq, political and security officials said.

In the week since national elections, police officers and Iraqi National Guardsmen said they have received more tips from the public, resulting in more arrests and greater effectiveness in their efforts to weaken the violent insurgency rocking the country...

...officials in Baghdad said a relative lull in violence in the capital has fueled the sense that something has fundamentally changed since the vote. A change of attitudes in Baghdad could make a crucial difference in the battle against the insurgency, and a buoyed sense of civic pride is already beginning to change the way the public treats the police, authorities say.

"They saw what we did for them in the election by providing safety, and now they understand this is their army and their sons," said Sgt. Haider Abudl Heidi, a National Guardsman wearing a flak jacket at a checkpoint in Baghdad.

Reports from Iraqis reflected a similar shift in attitudes in large areas of the north and south, although authorities acknowledged that in some parts of the country, people remain hostile to the emerging Iraqi authority and supportive, to varying degrees, of the insurgents.

The insurgency began to emerge soon after the toppling of Saddam Hussein, on a tide of anger over the U.S. occupation. But in interviews over the past week, officials and Baghdad residents cited what they called a renewed nationalist pride since the elections that they said may be dampening anti-American sentiment, and may be starting to dispel Iraqi tolerance and support for the insurgents.

"I feel very optimistic that things will change for the better because of the strong turnout in the elections. That reinforced our faith and gave us a sense of change for the better," said Ali Jassem, 32, the manager of a bakery in Baghdad.

"You can feel the situation has changed," said Haider Abdul Hussein, 30, a pharmacy owner. "People seem to linger on the street longer. You can feel the momentum, the sense of optimism."

Part of that mood change is credited to Abdul Amir, Iraq's newest national hero. On election day, Amir, 30, a policeman in Baghdad, noticed a man walking toward a polling station who appeared to be carrying something heavy under his coat. Amir wrapped his arms around the man and dragged him away from the crowd. A belt of explosives wrapped around the man blew both men to shreds.

Members of Iraq's interim cabinet have touted Amir as a symbol of national pride. Newspapers have been filled with stories about him. A statue is being planned, and the elementary school that served as the polling station where he died may change its name to honor him...
