While this is considered donating to a nonprofit, I don't see it as being any different than buying tickets to all the other entertainment venues in town then expecting to deduct them from my taxes. Clearly the Republicans are trying to stick it to the wealthy. Haha.
I don't see it being a big deal because people with that kind of money don't need the deduction.
What I do see is the University making the stadium more comfortable and concessions more accessible.
There also seems to be a grey area where they could possibly redesign the donation so it goes directly to academics and thus is still tax-deductible??
