We have the precedent of the election taking place on schedule during the War of 1861-1865. Even if either candidate died immediately before the election, people vote for electors, who use their best judgement. I suppose for the Republicans it would be Pence, and Sessions would be sensible VP choice. For the Dems? Who the heck knows? Kaine is no unifier, but they might have to go with him anyway.
Yes! I for one certainly wished for Senator Jeff Sessions, over Pence, as VP. Pence is a real yawner, probably a fine man. Certainly he was not all that energetic on social issues in his state, but these days they are all a compromise, or they get replaced with Marx type clones.
