It is about perception and reality.
FYI, whether it matters to you or not:
Between 2000 and 2004, Barack and Michelle Obama gave less than 1% of their income to charity.
It was 5% in 2005, 6% in 2006.
In 2006, Dick and Lynne Cheney gave 78% of their income to charity. (That's not a misprint.)
One is of course a prophet of change and peace; the other is a Grinch-demon warlord thirsty for blood and oil and the bones of small children.
