Greedy, weird little bastards
Mr. and Mrs. Paul Ryan gave a whopping 1.2% of their 2010 income to charity. In 2011, when they realized people may soon inquire about such giving, those charitable contributions increased to 4%. Over the two years the Ryan's averaged a whopping 2.9% of their $538,000 income. That's far from tithing.
The Romneys get millions of dollars in tax breaks for their 'charitable' contributions. Of course, it all goes to the Mormon Church, which is really just money for a cult center to build more shrines for fucking weirdos, and not charity, but they get the deductions anyway.
