President Obama and Mitt Romney crisscrossed the country to energize supporters as new polls forecast a down-to-the-wire election. A new Wall Street Journal/NBC News poll of likely voters finds Mr. Obama leading his rival by a nose, 48% to 47%.
The Romney camp, combing through surveys taken in the waning days of the campaign, pointed to strength among independent voters, anxiety over the economy and greater enthusiasm among conservatives as signs that the Republican would win, potentially with victories in states such as Pennsylvania and Minnesota that a GOP presidential candidate hasn't carried for decades.
Obama aides exuded similar confidence, citing polls showing the president remains resilient in potentially decisive states such as Ohio and Virginia. The campaign's elaborate ground operation, they said, would mobilize Mr. Obama's core set of minority, young and female voters to guarantee an Obama victory.
