SEATTLE — President Barack Obama is addressing his most solidly supportive constituency, black voters, as he wraps up a four-day, five-state trip.

After a fundraising swing through the Seattle and Portland, Ore., Obama was flying to New Orleans on Wednesday to address the National Urban League, a civil rights group.

While enthusiasm among some Obama supporters has faded since 2008, support for America's first black president remains high among African-Americans. In a recent Associated Press-GfK poll, 82 percent of black adults said they would vote for Obama. His approval rating among blacks was 87 percent.

Obama skipped an appearance at the NAACP earlier this month, raising questions about whether his campaign was taking black voters for granted. The White House blamed a scheduling conflict and sent Vice President Joe Biden to address the nation's oldest civil rights organization instead.

Republican challenger Mitt Romney also addressed the National Association for the Advancement of Colored People, raising eyebrows when he told the crowd: "If you want a president who will make things better in the African-American community, you are looking at him."

The audience booed the presumptive Republican nominee when he said he would repeal "Obamacare" — the name critics use for Obama's health care overhaul — if elected.

Obama also was raising campaign money at two separate stops while in New Orleans: an intimate 20-person event at the cost of $25,000 per person, and a larger event at the House of Blues for 400 people, with tickets starting at $250.

Obama raised at least $6 million at events this week in California, Oregon and Washington. The president started the trip Sunday with a stop in Colorado to meet with survivors and families of the victims of last week's movie theater massacre.
