Simmons has given to political campaigns since the late 1980s and previously supported Gingrich's old political action group, GOPAC, according to Mother Jones. Forbes estimates Simmons' worth at $9 billion. Contran has stakes in chemicals, metals, waste management, computer support systems, fencing, wire, and security products, according to Hoover's.
While the super PAC boosting Mitt Romney's campaign, "Restore Our Future," didn't receive any funds from Simmons or Adelson, the group did garner the most $1 million gifts in 2011 - ten, from a combination of individuals and companies. In fact, those seven-figure donors represent one-third of the $30 million raised by the group last year.
Another big Restore Our Future Donor, Frank Vandersloot, is a national finance co-chair for the Romney campaign. Vandersloot is the CEO of Idaho Falls-based Melaleuca companies, manufacturers of nutritional and pharmaceutical products, which gave the pro-Romney Super PAC $1 million.
