You're right, something has to be done with Buchanan. Secretary of State would seem to be the poisition he would be entitled to as Dole's running mate, but Dole isn't going to do that (remember Dole doesn't really like Buchanan but was talked into picking him by the party bosses).
Ambassador to the U.N? (Just kidding). Actually, your idea of making him an ambassador to some place where ambassadors don't matter sounds good, but that may not be enough for him.
See, the idea of putting Buchanan into any senior diplomatic position seems like a punchline. He would have a claim on State, you're right, but his views are well outside the mainstream of the party. His only real claim on the Republican base is social conservatism, and there's no Secretary of Bedrooms. The Holy See would be suited to his ultra-Catholicism and it's a reasonably high-stature position.
Maybe give him a cabinet post that no one cares about. Transportation? Interior? Energy?
Well, it can't look like a snub. Does Buchanan even have views on transportation or energy? Secretary of Labor seems to suit his interests best, but again: he needs to be acceptable to the party as a whole. Still, if he shuts up and spends his time simply throwing red meat to working-class voters he could be quite effective in Labor.
Everyone let me know what you think about this.
I'm really glad you've resumed this -- one of my favourite TLs on the board, and it just gets more interesting every week. New updates eagerly awaited.
