Clinton, a Democrat who lives in the suburbs, told the Times in an interview she does not like Bloomberg's effort to have the law reversed by the city council so he can seek a third term. The council began public hearings on the move Thursday.
"It is disturbing that voters voted twice, so I think that the City Council and the mayor have to first go through the hearings they're holding and try to figure out what they will do," she said. "They have the legal authority to make the change that they're considering, but I really am going to watch from the sidelines now because this is a very intense, local debate and the people of New York City should be heard."
Bloomberg ran for mayor as a Republican but became an independent in his second term.
Also Thursday, aides to Tom Golisano, a Rochester businessman who has donated heavily to Democratic state legislators, told the Times he plans an advertising campaign supporting term limits. Golisano, like Bloomberg, is a billionaire.
