Not sure how politics play into cord cutting; end of the day, that's what's at the heart of the crisis ESPN is facing.
And saying "leave politics out of (whatever)" is typically pretty fruitless. I realize I'm saying this as a civics teacher, but the textbooks all say it clearly: like it or not, everything is political. Not everything has to be partisan, of course, but everything, including sports in a very big way, is political.
Regardless, though, again, politics on a sports channel, whatever they might be, won't be the big factor driving cord cutters.
