agreed. If the deduction was the primary reason to be a TM, they could simply donate to at their home church or school or whatever.
I would presume that people are TM's because they are incredibly passionate about NDSU and want season tickets with little to no impact of the deduction. could it effect some people's tax situation? It is a possibility to be sure, however I would be shocked if this has any significant impact on the quantity of donations or TM members. I would presume those who are TM's will want to donate to keep receiving tickets and perks regardless of the deduction. Plus if they are so wealthy, the bill allegedly helps them save the most tax, so they simply may not care
I could be way off but time will tell
