From 2007 to 2009, Santorum’s rate of charitable giving fluctuated between 2.03% and 2.67% of his earnings.
In 2010, the rate dropped to 1.76% of his $923,411 in income. That same year, President Obama gave 14.2% of his income to charity, while Mitt Romney donated 13.8% and Newt Gingrich gave 2.6%.
Now, in fairness, I don’t give a whole lot to charity, but then I’m one of those schmucks who sometimes doesn’t fill up his gas tank to save a few bucks.
Also in fairness, almost all of Romney’s donations went to the Mormon Church, so I’m not sure that number is quite representative.
