Ward 7 Councilmember Kevin P. Chavous knows that his support for federally funded school vouchers hasn’t endeared him to some of his constituents. “It’s no secret that a large majority of folks in my ward are against vouchers,” the councilmember said last month. “I’m completely motivated by what I feel is right.” “Right,” in this case, is a double-entendre. The controversial public-policy position has turned the east-of-the-river Democrat into a local hero of Republican school-choice advocates. And they want to reward Chavous, who is suffering through a dismal fundraising season, for his daring stance: Voucher proponents such as C. Boyden Gray, former counsel to President George H.W. Bush, will host a fundraiser for Chavous Thursday evening in Georgetown. “I don’t have anything to say about it,” Chavous says. —Elissa Silverman
