I didn't do any update on the Martin Luther Mitt story because I thought it a bit weird that a new org. (okay, it's The Politico, but still) was actually relying on eyewitness accounts from 44 years go to "debunk" the debunking. Unsurprisingly, Drudgico got punk'd.
As I've said several times, contra some I worry about Mitt as a candidate despite the Mormonism because of his willingness to lie about literally everything. It's a powerful skill, made even more powerful when you have media allies who will launder those lies for you.
