A hypocrisy would be Obama criticizing Romney for taking PE money and then doing it himself. Or if he criticized PE for doing things that he did himself (this would probably be your best argument as the government did make similar moves to what it appears Obama is campaigning against when it took control of the automakers).
But for you to say someone cannot accept money from a person or organization who does not share the same economic philosophy...well, that's unAmerican. But who knows, maybe this will catch on. I can't wait to see the church basket being passed around with a sign that says "Please don't put any money in this if you made your money sinning." I guess ND won't accept tuition money from the fertility doctor.
