Hillary Clinton, 2016 Democratic presidential nominee, right, and U.S. President Barack Obama wave to the crowd during a campaign event in Philadelphia, Pennsylvania, U.S., on Monday, Nov. 7, 2016. Clinton leads Donald Trump by three percentage points among likely voters nationally, the latest sign that her campaign's painstaking focus on women, Latinos, and blacks could help propel her to the White House.
