IT'S OBAMA; Decisive victory makes history;In California, gay-marriage ban takes early lead

With Obama leading every preelection poll, his hometown of Chicago was primed for a celebration. Downtown skyscrapers stayed lighted for the occasion on an improbably warm November night. At Grant Park, giant video screens were tuned to CNN, and raucous cheers erupted each time a state fell Obama's way, until finally victory came just a few moments after polls closed on the West Coast.

Shortly after, Arizona Sen. McCain called the president-elect to concede. President Bush then telephoned with his congratulations.

In Phoenix, McCain, 72, delivered a gracious concession speech that nodded to history and his erstwhile foe.

"We have come to the end of a long journey," a somber McCain said. "The American people have spoken, and they have spoken clearly. This is an historic election, and I recognize the special significance it has for African Americans and the special pride that must be theirs tonight."

He shushed the crowd when they booed Obama -- "Please," McCain said, motioning for silence -- and urged them to join him in working with the incoming president for the greater good of the country. "Whatever our differences," McCain said, "we are fellow Americans."

McCain, burdened by his party's frayed image, prevailed in a band of states that make up a shrinking Republican base, mainly in the South, the Plains and parts of the interior West.

Two of the hardest-fought states -- North Carolina and Missouri -- were too close to call.

For most voters, the sagging economy was the topmost concern -- a dynamic that played strongly to the Democrat's favor. Six in 10 voters said the economy was the most important issue facing the nation, according to exit polls -- far more than cited energy, Iraq, terrorism or healthcare.

Obama alluded to those worries and others in his victory speech, offering a note of sobriety amid the celebration.

"The road ahead will be long," he said. "Our climb will be steep. We may not get there in one year, or even one term. But America, I have never been more hopeful than I am tonight that we will get there. I promise you, we as a people will get there."

Voters flocked to the polls in record numbers Tuesday, continuing a pattern of electoral exuberance that started in the primary season.

There were scattered voting problems reported throughout the day, including long lines, malfunctioning voting machines and mislaid ballots. But there was nothing like Florida's infamous "butterfly ballot" fiasco, which sent the 2000 presidential contest into several weeks of overtime before the U.S. Supreme Court stepped in to settle the race.
