The race for the Republican nomination for mayor of Philadelphia remains to close to call this afternoon.

With results from 57 precincts still out, Karen Brown, the party-backed candidate, leads John Featherman by only 52 votes.

Brown was a Democrat recruited by the party to be its mayoral candidate. Featherman was backed by the Loyal Opposition, an insurgent group that believes the GOP has become irrelevant in Philadelphia and needs to be revived.

Whoever wins is expected to fall to Mayor Nutter in November.
