(CNN) - President Obama's decision to release his birth certificate appears to have satisfied all but a tiny fringe who continue to believe he was not born in America.
According to a recently released Washington Post poll, only 3 percent of Americans now believe the president was born abroad while 77 percent say he was definitely born in the United States. Nearly 20 percent have no opinion on that matter.
A similar Washington Post poll conducted a year ago found 14 percent of Americans believed the president was born in another country while 68 percent thought he was born in the United States.
Obama released his birth certificate last week, saying the controversy surrounding the issue had become a "sideshow."
The surprise release followed recent and sustained remarks by businessman Donald Trump, among others, raising doubts as to whether the president was born in the United States.
The poll was conducted April 28-May 1 and surveyed 1,006 Americans by telephone. It carries a sampling error of plus or minus 3.5 percentage points.
