Wealth:

Undisclosed.

Power/Influence:

One of the GOP’s most prominent money men, Reynolds has access to thousands of well-heeled donors around the country — particularly past supporters of George W. Bush. Reynolds’ ties to President Bush go back to his Texas days running Arbusto Energy, an oil company founded by Bush. As the company teetered near insolvency, Reynolds’ Spectrum 7 oil company bought out Arbusto. Later, Reynolds was a key investor in Bush’s purchase of the Texas Rangers baseball team.

Role in Campaign ’08:

He became McCain’s national finance co-chair in mid-February and helped McCain raise more than $50 million.

Who Knew: Reynolds was the driving force behind the creation of Reynolds Plantation, an 8,000-acre lake and golf community built on Lake Oconee, east of Atlanta, Ga.
