WASHINGTON (AP) — A new poll finds Barack Obama is leading John McCain nationally by 6 percentage points thanks to big leads he is enjoying among women, minorities and younger voters.

The Associated Press-Ipsos poll shows that Obama is leading his Republican rival 47 percent to 41 percent. McCain has a 10-point lead among whites and is tied with the Democrat among men, but Obama is leading by 13 points among women and has huge leads with minorities and the young.

The poll was released Tuesday following a week in which the two camps accused each other of bringing race into a campaign in which Obama is seeking to become the country's first African-American president.
