Brazile called the campaign "cause for alarm" among Democrats because it puts them at risk of losing a larger share of their most loyal political constituency, the Washington Times reported Thursday.
"It won't take much for the GOP to garner 12 percent to 15 percent of the black vote in future elections, as some blacks are starting to believe the community is not well-served when one party takes their votes for granted and the other party doesn't work to earn them," she wrote in her weekly opinion column.
At a recent civil rights forum in Atlanta, Brazile said she was surprised to discover she and other panelists found the need to discuss "new players in the dialogue -- blacks who lean Republican."
