President Obama, and First Lady Michelle Obama.
The wealthiest couple, Mitt Romney and wife Ann, finished slightly ahead, giving 13.8 percent to charity — most of it to the Mormon church. Of course, Romney also made far more than anyone else in 2010, at more than $21 million.
But when you calculate charitable giving based on adjustable gross income, Obama actually takes a lead. He and Michelle gave 14.2 percent of their AGI, while the Romneys gave 13.8 percent.
Santorum and Newt Gingrich, by comparison, gave very little of their income to charity.
Gingrich and his wife, Callista, gave 2.6 percent of their $3.2 million income in 2010.
By the way, most of Romney’s charitable funds went to the Mormon Church.
