The problem for Mitch is two fold: He cannot come out and say it's Donald Trump's fault that the Republican Party is nominating sanctimonious fascists, crack pots, and delusional election deniers as congressional and senatorial candidates without putting himself on the MAGA Mob's hit list. Furthermore, Moscow Mitch is culpable of empowering the lunatics who made Donald Trump the unquestioned leader of the Republican Party.
When Moscow Mitch and the party establishment decided not to convict Trump of his crimes during the impeachment trials, and they started treating Trump’s attempted coup as a minor detail they could brush aside, the consequences were foreseeable: their cowardly acquiescence ceded the argument over the 2020 election to Trump and allowed his power over the Republican Party to go unchallenged. Predictably, Trump used that power to endorse primary candidates such as election denier Kari Lake and Christian Nationalist – NAZI Sympathizer Doug Mastriano without so much as a whimper from any other leader of the party. That would be perfectly fine with Moscow Mitch if those horrible candidates could win, but it is now more than likely that Republicans are going to lose elections that could have been won by reasonable candidates – at least that is what Moscow Mitch wants his fellow Republicans to believe.
This is serious business. Mitch McConnell is all about the power, his (Mitch's) power! In politics you have the power people think you have – no more, no less. You are in trouble as a political leader if people question your judgment or your power. Unfortunately for Mitch, the mid term election polls are hitting him in the face like a stiff breeze coming by way of the garbage dump! And the odor is setting off the panic alarm in his mind! ”Oh Shit! You don't think the Party will blame me for pissing off the broads by packing the supreme court with sanctimonious fascist justices who took away the protection of a woman's right to control her body and make her reproductive choices without the interference of any government, do you?” God no, Mitch! They can't do that, not when so many of them are advocating the sort of draconian prohibitions that were forbidden by Roe v. Wade. That may sound like a typical Republican retort, but Moscow Mitch knows that the “et tu” argument does not wash away the blame; it just spreads it around a bit. So Mitch has to deflect. He cannot allow people to blame the likely Republican loses on a reaction to the Dobbs decision. It has to be the result of someone, not Moscow Mitch, helping unelectable candidates get nominated to represent the party! “It's on you,” Moscow Mitch wants to shout, “you unmentionable whoever!”
