Some of Mitt Romney’s largest Massachusetts financial backers are well known. His former partners at Bain Capital have given more than $3.3 million. New Balance chairman Jim Davis gave $500,000, and retired Reebok International chief Paul Fireman has contributed $250,000.
Their support is public because they have given money to a Romney super PAC, which is required under federal law to disclose the gifts it receives. But there is a whole other swath of influential Romney supporters whose names voters can only guess at, because the campaign refuses to reveal them.
