Hmmm….I wouldn’t put it past them:

It has unfolded mostly under the radar. But an important development in the 2008 Democratic battle may be the building backlash among African Americans over comments from associates of Sen. Hillary Rodham Clinton that could be construed as jabs at Sen. Barack Obama’s race.
These officials, including Clinton aides and prominent surrogates, have raised questions or dropped references about Obama’s position on sentencing guidelines for crack vs. powder cocaine offenses; on his handgun control record; and on his admitted use of drugs as a youth. The context was always Obama’s “electability.” But the Illinois senator’s campaign advisers said some African American leaders detect a pattern, and they believe it could erode Clinton’s strong base of black support.
