Mayor Thomas M. Menino said that Hillary Clinton should not run for vice president on a ticket with Barack Obama because her husband, former president Bill Clinton, could cause problems for the new administration.
"If she got back into the White House, she'd bring along Big Daddy, and he would overshadow the president," Menino said in an interview.
Bill Clinton is "pushing real hard" for his wife to be Obama's running mate, Time magazine reported this week.
Menino, 65, was reelected to his fourth term as mayor in 2005. He endorsed Senator Hillary Clinton, Democrat of New York, in 2007 and is a pledged Clinton delegate to the Democratic convention in August.
Clinton defeated Obama, Democrat of Illinois, in the Massachusetts primary Feb. 5, winning 56 percent of the vote.
Obama supporters in Massachusetts include Senators Edward M. Kennedy and John F. Kerry and Governor Deval Patrick. Obama has a majority of pledged delegates to the Democratic National Convention.
Menino's pick for an Obama running mate is former presidential candidate Senator Joseph Biden of Delaware.
"He's smart, he's got the foreign policy experience, and he can help win Pennsylvania," his neighboring state, for Obama in the general election, Menino said.
He praised both Clintons, crediting them with creating prosperity and domestic security during the former president's two terms.
"When did America ever do better?" he said.
