YAY! Nice to know that there are still some who will stand up to the Obama machine!
It could simply be a business decision. NFL games are one of the few things on TV that aren’t racially divided (both blacks and whites watch) and attracts a wide age range, though mostly male. Promoting Obamacare could drive away conservative voters from watching, right before sweeps and the start of the next season.
So the financial cost is more than any incentives and brownie points with the fed.
