HARI SREENIVASAN: The president and his challenger spent only part of their day focused on foreign policy.
NewsHour correspondent Kwame Holman reports the domestic agenda was never far away, as the campaigning continued.
KWAME HOLMAN: Away from the U.N. stage, the president and Mrs. Obama targeted female voters in a taped appearance on ABC's "The View." They both focused again on who is best to revive the economy.
PRESIDENT BARACK OBAMA: We grow fastest when the middle class is doing well and when folks who are trying to get in the middle class have ladders of opportunity. So, that's a different vision about how we move the country forward.
And, ultimately, it is going to be up to the American people to make a decision about who has got the better plan.
MICHELLE OBAMA, first lady: I'm voting for him.
(CHEERING AND APPLAUSE)
KWAME HOLMAN: This morning, Republican Mitt Romney was welcomed warmly at the Clinton Global Initiative. The former president praised him for supporting the AmeriCorps program.
FORMER PRESIDENT BILL CLINTON: And, Governor, I thank you for being here. The podium is yours.
MITT ROMNEY (R): Thank you, Mr. President.
BILL CLINTON: Thank you.
KWAME HOLMAN: Romney returned the compliment with a joking reference to Clinton's speech nominating President Obama at the Democratic Convention.
MITT ROMNEY: If there's one thing we have learned in this election season, by the way, it is that a few words from Bill Clinton can do a man a lot of good.
MITT ROMNEY: All I have got to do now is wait a couple of days for that bounce to happen. So...
KWAME HOLMAN: From there, Romney turned to education policy at a forum sponsored by NBC News.
MITT ROMNEY: We have proven that sending a lot of money to failed schools to pay the same teachers to do the same things will not make any difference. The real key is leadership in drawing the best and brightest to the profession, giving them the right incentives, promoting the very best, helping our students have discipline in the classroom, insisting on the participation of parents.
KWAME HOLMAN: The candidate's New York City stops came as another poll, this one from The Washington Post, found Ohio swing toward the Obama column. No Republican has won the White House without Ohio.
With that in mind, Romney and running mate Paul Ryan began a bus tour through Ohio this afternoon.
HARI SREENIVASAN: The U.S. Supreme Court upheld West Virginia's congressional redistricting plan today.
Critics of the redistricting had argued that the populations within newly drawn districts were too far out of balance, but the Supreme Court reversed a lower court ruling and said the state's legislature was correct in trying to keep counties intact, keep incumbents from facing each other, and minimize shifts in population. The lower court may still consider challenges to the plan under the state constitution.
In economic news, a key index showed home prices rose again in July, another sign the housing market is on the road to recovery. And a separate index had consumer confidence rising in September.
But it wasn't enough to help Wall Street, amid new worries about Spain's debt troubles. The Dow Jones industrial average lost 101 points to close at 13,457. The Nasdaq fell 43 points to close above 3,117.
The National Football League faced an explosion of calls today to end a labor dispute with its referees after a mistake decided the Green Bay- Seattle game.
With seconds left, Seahawks quarterback Russell Wilson launched a Hail Mary pass into the end zone. Receiver Golden Tate was awarded the touchdown, even though a Packers player also grabbed the ball and appeared to control it.
The replacement officials had conflicting rulings, but they finally gave Seattle the score and the win 14-12. Today, the league acknowledged it was a bad call, but it let the result stand.
Starting today, anyone can hold Albert Einstein's brain in the palm of a hand. The National Museum of Health and Medicine in Chicago has launched an iPad app that includes 350 images of the famed scientist's brain. They show slices of brain tissue made after the Nobel winner died in 1955. In later years, a study found the part of Einstein's brain that aided in math and spatial relationships was larger than normal.
Those are some of the day's major stories.
