A proper letter to Mc Cain does not start with “Dear”.
It starts with FU.
I kind of was dismayed at the tone of the letter also. To me you don’t explain to an insane person why you are doing anything with him, to him, or for him, unless it’s just to shut him up and make it easier to put the straight jacket on him.
The explanation in the letter, while good, isn’t necessary because sanity, logic and reason don’t belong in a ‘conversation’ with a maniac.
Whenever and however anyone can, he needs to be ridiculed, repudiated and reviled for the batsh!t crazy fool that he is. His followers, those uninformed who elect him, need to be treated with amusement that they could even entertain the thought of voting for him and made felt ashamed.
He HAS to be primaried and defeated as soon as possible - no hold, no quarter, no sorrow.
