This is one of those moments in history when it is worth pausing to reflect on the basic facts:
An American with the name Barack Hussein Obama, the son of a white woman and a black man he barely knew, raised by his grandparents far outside the stream of American power and wealth, has been elected the 44th president of the United States.
Showing extraordinary focus and quiet certainty, Mr. Obama swept away one political presumption after another to defeat first Hillary Clinton, who wanted to be president so badly that she lost her bearings, and then John McCain, who forsook his principles for a campaign built on anger and fear.
His triumph was decisive and sweeping, because he saw what is wrong with America: the utter failure of government to protect its citizens. He offered a government that does not try to solve every problem but will do those things beyond the power of individual citizens: to regulate the economy fairly, keep the air clean and the food safe, ensure that the sick have access to health care, and educate children to compete in a globalized world.
Mr. Obama spoke candidly of the failure of Republican economic policies that promised to lift all Americans but left so many millions far behind. He committed himself to ending a bloody and pointless war. He promised to restore Americans’ civil liberties and their tattered reputation around the world.
With a message of hope and competence, he drew in legions of voters who had been disengaged and voiceless. The scenes on election night of young men and women, black and white, weeping and cheering in Chicago and New York and in Atlanta’s storied Ebenezer Baptist Church were powerful and deeply moving.
Mr. Obama inherits a terrible legacy. The nation is embroiled in two wars - one of necessity in Afghanistan and one of folly in Iraq. Mr. Obama’s challenge will be to manage an orderly withdrawal from Iraq without igniting new conflicts so the Pentagon can focus its resources on the real front in the war on terror, Afghanistan.
The campaign began with the war as its central focus. By Election Day, Americans were deeply anguished about their futures and the government’s failure to prevent an economic collapse fed by greed and an orgy of deregulation. Mr. Obama will have to move quickly to impose control, coherence, transparency and fairness on the Bush administration’s jumbled bailout plan.
His administration will also have to identify all of the ways that Americans’ basic rights and fundamental values have been violated and rein that dark work back in. Climate change is a global threat, and after years of denial and inaction, this country must take the lead on addressing it. America must develop new, cleaner energy technologies .
Mr. Obama also will have to rally sensible people to come up with immigration reform consistent with the values of a nation built by immigrants and refugees.
There are many other urgent problems that must be addressed.
Tens of millions of Americans lack health insurance, including some of the country’s most vulnerable citizens - children of the working poor.
Other Americans can barely pay for their insurance or are in danger of losing it along with their jobs. They must be protected.
Mr. Obama will now need the support of all Americans. Mr. McCain made an elegant concession speech in which he called on his followers not just to honor the vote, but to stand behind Mr. Obama. After a nasty, dispiriting campaign, he seemed on that stage to be the senator we long respected for his service to the United States and his willingness to compromise.
That is a start. The nation’s many challenges are beyond the reach of any one man, or any one political party.
