WASHINGTON — A month after the bitterly fought election, President Barack Obama has his highest approval ratings since the killing of Osama bin Laden, according to an Associated Press-GfK poll, and more Americans say the nation is heading in the right direction now than at any time since the start of his first term.

Obama’s approval rating stands at 57 percent, the highest since May 2011, when U.S. Navy SEALs killed the terror leader, and up 5 percentage points from before the election. And 42 percent say the country is on the right track, up from 35 percent in January 2009.

A majority think it’s likely that the president will be able to improve the economy in his second term.

Americans are divided on what kind of president Obama has been, with 37 percent saying he’s been above average or outstanding and 36 percent describing his tenure as below average or poor. Another quarter say he’s been just average.
