The buzz is Cal Cunningham faces an uphill battle in versus Elaine Marshall and Ken Lewis in Tuesday’s Senate primary:

Earlier Wednesday, a top adviser to Marshall’s campaign told POLITICO that Cunningham wouldn’t be able to win a general election because “he’s a white male.”

“He doesn’t have a base. If he gets two percent of the vote in the African American community in the primary, I’d be shocked,” Thomas Mills said of Cunningham. “And if African Americans don’t vote at 20 percent in the general, Democrats can’t win in this state anyhow.”

Last week, a Cunningham adviser was quoted in the Washington Post explaining his candidate’s unimpressive fundraising quarter this way: “When you are in a three-way Democratic primary with a female statewide office holder and an African American it makes it difficult to raise money no matter how good you are.”

Lewis interprets all this as interjecting race into the campaign. Interesting that he reportedly has the endorsement of former Sen. Carol Moseley Braun, who doesn’t whistle Dixie.
