—Perenchio, 81, gave $500,000 and has donated $3 million to Rove's group since 2010. He is a former chairman for the Spanish-language Univision television network. He was a top bundler for McCain's 2008 presidential campaign. Perenchio, who heads Chartwell Partners LLC, gave $10,000 last year to the National Republican Congressional Committee and $5,000 to the re-election campaign of House Speaker John Boehner.
—Harold Simmons, 80, gave $100,000 following an earlier $100,000 donation in January. He also gave $100,000 last month to Winning Our Future, the super PAC supporting Gingrich; his wife, Annette, gave $1 million to the Red, White and Blue Fund. A billionaire, Simmons was the top benefactor for Rove's group, providing $12 million between his personal checkbook and the coffers of Texas-based Contran Corp., a holding company with interests including chemicals and waste management.
Simmons rivaled Perry as a $4 million contributor to the Swift Boat group in 2004 and was a bundler for the Bush and McCain presidential campaigns. In addition to his $12 million donation to Rove's group, Simmons has also given more than $200,000 to GOP candidates and party PACS and groups.
All told, super PACs have provided essential support for many campaigns. Gingrich, the former House speaker and winner of the South Carolina and Georgia primaries, collected only $2.6 million last month while spending roughly $2.8 million during the same period, his campaign said. Santorum's own campaign pulled in about $8.9 million in contributions during the same period, when he saw a surge in support.
