Hint: it is not the African-American community.

In 2008, Barack Obama rode a tidal wave of support from blacks and Hispanics. But both elements of his base are having second thoughts according to pollsters, at least as refletced in their "approval" ratings. But there is opne group that is holding firm: Muslim Americans. Investor's Business Daily reports:

When Barack Hussein Obama first stepped into office in January 2009, he had 92% approval among blacks, 75% approval among Hispanics and 58% approval among whites, according to Gallup.

Since then, his monthly approval has dropped eight points among blacks, 27 points among Hispanics and 25 points among whites. (snip)

Last month, Pew Research Center released a survey of U.S. Muslims that was almost universally overlooked. It found that Muslims overwhelmingly approve of the way Obama is handling his job as president. Fully three-quarters (76%) favor him, compared with just 46% of the general public.
