Romney's No. 4
Robert Rowling, 58, head of Dallas-based TRT Holdings.
Total: $4.1 million
Rowling has given at least $4.1 million to Republican Party and candidates this election. Most of his donations, $4 million, went to Rove's American Crossroads, both through personal donations and through his firm. Rowling also has given $100,000 to the pro-Romney Restore Our Future super PAC. Rowling's holdings are worth an estimated $4.8 billion and include Omni Hotels, Gold's Gym and Tana Exploration, his family's oil company. Rowling once told the Texas Tribune he prefers political donations to lobbying efforts. Rowling has been a big donor in Texas political circles, winning a role for Omni as operator of Dallas' convention center hotel after a 2009 city referendum fight.
