I've toyed with trying to make a TL on this, but does anyone have any times where it would be even plausible that a noncongress person would be elected Speaker of the House? It's allowed, but outside of a retired US President, I can't see it.
This would be very unlikely, but maybe if the GOP took the house in the 80s (I know you'd need a drastic change in mid-80s politics) during Reagan's Presidency, Ford could be selected as a compromise candidate.
