From the Daily News:
Since the Democrat-turned-Republican-turned-Independent mayor ditched the GOP in June 2007 to prepare for a never-realized run for President, he now needs permission from three of the city's five GOP party chairs to run on the ballot line he had for his 2001 and 2005 campaigns.
But at least three of the chairmen, who represent Brooklyn, Queens and the Bronx, are so angry with the mayor for a host of transgressions - failing to provide patronage jobs, proposing congestion pricing, ramming through the term limits extension to allow his reelection bid - that they might not support him.
"The three Republican chairmen would love nothing more than to support John Catsimatidis for mayor," a highly-placed GOP source said. "If we could all agree on a Democratic candidate, we might even back him."
