"The people who are at the top are running the Republican Party into the ground," said Featherman, adding that GOP voters regard Brown's bid as a fraud.
Brown, who had tried to run for City Council as a Democrat, dismissed Featherman's complaints and said GOP leaders "have been exceptional with me. They've welcomed me with open arms."
Featherman filed 2,060 signatures; Brown filed 1,494.
The Republican races for mayor, city commissioner and Council at-large are believed to be the first contested primary spots since 1991, when three GOP heavyweights - former Mayor Frank Rizzo, former District Attorney Ron Castille and businessman Sam Katz - went after the mayoral nomination.
The contests reflect a continuing split in the city GOP, between the established organization, led by general counsel Michael Meehan and chairman Vito Canuso, and a faction unhappy with their leadership.
Both parties will choose two candidates for city commissioner, and in the general election, the top three vote-getters will get the jobs, guaranteeing that all the seats won't be held by the same political party.
On the Democratic side, incumbents Marge Tartaglione and Anthony Clark, both ward leaders, are seeking re-election, Tartaglione to her 10th term, Clark to his second. They're opposed by another Democratic ward leader, Stephanie Singer, and four other Democrats: Ivy Staten, Michael Edward Bell, Bernard Talmadge and Warren Bloom.
There are four Republican candidates for commissioner - incumbent Joseph Duda, a Republican ward leader from the Far Northeast, along with attorney James Mugford, both backed by the Republican organization. They're opposed by Al Schmidt, a leader of the anti-Meehan faction, and Marie Delany, director of a transitional facility in Frankford for women with children.
All five incumbent Democrats - Wilson Goode Jr., Jim Kenney, Blondell Reynolds Brown, Bill Greenlee and Bill Green - are trying to hold onto their seats.
Sixteen other Democrats filed petitions to challenge them: Ralph Blakney, Lawrence Clark, Sherrie Cohen, Francis Graff Jr., Ralanda King, Daryl LaFountain, Janis Manson, Edward Nesmith, Donna Gentile O'Donnell, Humberto Perez, Denise Ripley, Isaiah Thomas, Andrew Toy, Alexander Wilson, Louis Borda and Michael Jones.
On the Republican side, Frank Rizzo is seeking a fourth term, with nine other Republicans vying for the five GOP ballot spots. The others are John Giordano, Malcolm Lazin, Joseph McColgan, Elmer Money, state Rep. Denny O'Brien, Stephen Odabashian, David Oh, Al Taubenberger and Michael Untermeyer.
