“lack of political insight”
Translation: “He has NO idea what is really going on”
McConnell is/was a process guy, which is why he was so good with the judges. He knew how to work that process. Beyond that, he is inept, unable or unwilling to adapt to the change to democrats use of dishonorable tactics. He could be robbed, beaten, and held at gun point by Schumer and he’d be crowing about a lack of decorum.
