Only three percent of American voters said they feel the president's words and actions have had a negative effect on white supremacists; 35 percent said they felt the president's statements have had no impact on white supremacists or similarly polarized political action groups.
He also gets a negative 59% rating on his overall job approval - down from a 57% approval rating on August 17th.
