OXON HILL, Md. (AP) — Republican National Committee chairman Michael Steele’s bid for re-election looks in serious doubt, but it’s not clear which of his rivals has a clear advantage heading into balloting.

Steele sought support from his party’s members on Thursday after a gaffe-filled and costly two years. Four challengers campaigned to replace him in an unpredictable race to lead the party into the 2012 presidential and congressional campaigns.

The rivals included Wisconsin GOP chairman Reince Priebus, former Missouri chairwoman Ann Wagner and former Michigan chairman Saul Anuzis. Former Bush administration official Maria Cino also is seeking the job when 168 RNC members vote on Friday.

Each would face at least $15 million in RNC debt and demoralized donors who are frustrated with Steele’s management.
