Thomas Stemberg, co-founder ofStaples Inc. (SPLS), last month cut his 17th check to support Mitt Romney’s quest for the presidency. He wrote his first one nine years ago.
Stemberg, now managing general partner at the Cambridge, Massachusetts-based Highland Consumer Fund, is one of 40 donors who have been underwriting Romney’s White House ambitions for almost a decade. Since 2004, they have made a combined $11 million in donations as a down payment on Romney’s political future. Stemberg’s stake, so far, is $100,000.
