The NFL is a lost cause, gave up without a fight. NASCAR heading the same direction. I think the only sport not to have caved yet might be Hockey, though I don’t know for sure. As all this happens, I look for more and more obscure sports that the left ignores.
In my area (northern NJ) hockey wasn’t helped when the NJ Devils moved from the Meadowlands to Newark. They didn’t fare so well in the Meadowlands (a situation best described to me as them being the third team in a market with room for two - the NY Rangers and Islanders); when they won their first Stanley Cup they literally had the parade in the parking lot around the arena - which is not in a residential area, but a swamp. They were pressured to move into Newark, which has 0 hockey fans; they can’t give tickets away. On top of that, “Euro-Americans” are evacuating the whole NYC metro area in general. Newark tried the same tactic with the NJ Nets basketball team, but their Russian owner knew Newark had no future (plenty of basketball fans, but no paying customers) and promptly moved that team to Brooklyn.
