Names of dozens of executives who regularly appear in the news - and many others who remain under the radar - showed up on federal campaign finance reports filed July 15. While former Secretary of State Hillary Clinton leads in Florida fundraising overall - including drawing the maximum donation from HSN Inc. CEO Mindy Grossman - former Florida Gov. Jeb Bush appears to dominate among Tampa Bay business leaders, with leaders of Publix Super Markets Inc. and real estate and financial firms contributing to the Bush campaign. Florida Sen. Marco Rubio is off to a slower start among local business leaders.
