I mean he IS weak politically speaking. The party he is a part of view him as a usurper and seek to constantly undercut him
Hillary Clinton would have already killed McConnell. He is old and has lots of health problems. Easy peesy.
He pretty clearly doesnt have the strength to accomplish all of his goals, so he has to pick and choose. He also has a soft spot for retarded boomer shit. He chooses dumb shit to focus on. He doesnt even have a guy to accident people for him. To put it in perspective Sam Altman has a "have people commit suicide with gunshots in the back of the head guy".
For McConnell he needs to make it clear that he will rape McConnells patronage network in Kentucky and get those people to put pressure on him. McConnel is on deaths door and his caretakers can be fucked with. For Curtis a call to LDS and they can have the same revelation they had about niggers when they got threatened to have their shit looked at. Murkowskis McConnells bitch and will do what he says.
He can also set the tone with aipac and tie Israel aid to them lobbying for his domestic agenda.
He does none of these things.
