Hate to break this to everyone, but there's a picture with Shaw....and Busch...smiling broadly with Kirk at Wrigley.
This is obviously a case where you've got to separate the players from rooting for the team. There's a lot of support for Trump and guys like Kirk in the pro athlete ranks. Could be even more Cubs. Cubs ownership is also strongly tied to the right. I know for me, being a Cub fan isn't optional, it's learned behavior from childhood for better or worse. I couldn't stop rooting for them even if I tried. So you root for the jersey and what the organization itself has meant to you. The current players come & go.
