I'm cool with what he did, its a choice and as JCB mentioned it was a team invite not individual. As far as mixing sports and politics it has been going on for years. GW attending a NASCAR race, Michelle O doing the same thing. Barry O and the NBA. Barry O doing march madness brackets or talking about college football and on and on....Just the appearance of the potus at certain events leans toward campaigning for votes or showing love to his base voters.
To me, they have no place doing any of this. The country is in trouble and the last thing I want to see is the potus yuckin it up with sports figures. Jmo.
