Joan Walsh is a of a mind to spank Chris Christie for being an avowed Cowboys fan, and there's something weird about this that brings to mind the current state of NFL fandom.
NFL fans don't care about these three things--politics, concussions, or winning. They want to see their team and that's the tribe they identify with. If their team is losing, and is staffed with losers, they will rail about the owner or the coach but they'll still buy the gear and they'll still come back to the games. If the old timers come on and complain about being hit in the head twenty-six times in one week, they'll nod sagely and flip over to the other game and do nothing.
Nobody cares about politics so if Chris Christie is seen putting a body on Jerry Jones, so what? It's a free country. You can like whatever team you want.
