I haven't looked at the return but I know from personal experience that, if his charitable donations were in the form of appreciated securities [and they should have been] then there is a deductibility limit of 30% of income. The excess can be carried forward into future years.
I don't know about that stuff. But I do know these libs whined about taxes for weeks on end. And what do we get today? Threads about his ran, something about the military and hanging chairs.
