How do you know? Did you ask Coach about his intent? The subject was about folks who are leaving office going forward. Not who left office last year. If he was drawing a comparison, he could easily have mentioned it. I am sure Coach will be very glad to know you defended his statement.

If you're familiar with them, it's blatantly obvious.
You wanted to insult Coach, but since you were not familiar with why Cheney and Kinzinger were specifically chosen, you got it wrong.
