To my best knowledge, POTUS spent more Sundays on golf course than attending church services for the past 3 and 1/2 years.
POTUS (or candidate Obama) began to give money to charity when he decided to run for the White House in 2006.
It is absolutely true that Democrats are Christians too. But when contrasting Republican/Democratic POTUS/VPOTUS personal matters and their advocacy, then preference become obvious.
Do anyone recall the tax returns of the Born-Again Christian POTUS GW and VP Dick when they ran for office in 1999/2000?
