And I do not expect a miraculous conversion on his part, Papal advisors or not.

(And yes, the metaphor of Macbeth the Play (let alone the historical character) is stretched vey thin here).

Here's the primary difference - Vance would be at best a conservative president, and I don't think he would necessarily be among the mental giants in the presidential lists, but at the same time, he's not an aging vindictive sociopathic blackmailing malignant narcissist facing clear cognitive decline. Moreover, the MAGA base DESPISES him. Trump doesn't need allies - he has blackmail on everyone, and uses extortion and threats of violence in a manner that's right out of the Mafia Playbook. While Trump lives, he's not going to give that up, and he's certainly not going to give that power to Vance, who he likely sees now as a threat.

My belief is that Vance would likely be historically most like Gerald Ford in the aftermath of Nixon's resignation - an accidental president, especially if the Dems retake the House and possibly the Senate in the midterms (and we're not in the midst of a hot civil war by then).
