Nashville mayoral candidate David Fox Until now, the officially nonpartisan mayoral runoff in Nashville, Tennessee, hasn't been particularly ugly, but that all changed Monday. Conservative candidate David Fox had already been attacking runoff rival Megan Barry as unacceptably liberal on economic matters, but now he's descended to new depths by depicting Barry as an anti-Christian extremist. Fox's new radio ad aimed at African-American voters begins with the narrator accusing Barry of doing little to help black voters and gets much worse from there: We might see Megan Barry around election time, but when the election's over, she's gone.
