by Max AbelsonMaurice “Hank” Greenberg, the insurance titan whose CV Starr & Co. gave $10 million to a super-PAC backing Jeb Bush’s presidential bid less than four months ago, will probably support his Republican rival Marco Rubio.Greenberg, one of the biggest contributors to the 2016 race for the White House, said in a television interview with Betty Liu aired Wednesday that he’ll decide after votes in another “one or two states.” The New Hampshire primary is next week.Rubio, the Florida senator, came in third in Monday’s Iowa caucuses, just behind billionaire Donald Trump. Bush came in sixth, with about 3 percent of the vote. Greenberg, 90, built American International Group Inc. into the world’s largest insurer and has been waging one of Wall Street’s longest battles after losing control of it a decade ago.
