President Obama’s approval rating spiked into positive territory last week, and he’s since managed to build on those gains, according to the latest Gallup three-day rolling average.

Forty-nine percent said they approved of the job the president is doing, while 43 percent said they disapproved, Gallup found.

The positive 6-point margin is Obama’s best since last June, when his approval rating was briefly buoyed by the assassination of Osama bin Laden.

Gallup’s three-day rolling average has been susceptible to dramatic swings this year, which have typically been ironed out within a few days.

But last Wednesday, the president’s favorability swung sharply into positive territory, and rather than falling back to near break even, he’s managed to build on those gains in the days since.

Obama’s approval rating has been trending upward since bottoming out last August, when only 38 percent said they approved, versus 55 percent who disapproved.

Those numbers followed the contentious debt-ceiling debate and the U.S. debt downgrade, but the president’s rating had been rising steadily since then, likely buoyed by the brightening economy.

The president’s approval rating went positive on Jan. 1, after Republicans botched the politics on an extension of the payroll tax break just before Christmas.

In February, Obama’s approval rating averaged 45 percent positive and 47 percent negative.

Gallup's tracking poll has a 3-point margin of error.
