If our result is different from reality, would that person be included in the poll next election as president?
Hadn't planned on it, no -- it's tempting, but I'd like to see how each election goes as is. (Frex, I'm curious to see how people vote in '72, but it won't be nearly as fun if it's Nixon-Humphrey redux.)
After this, I might do a more "interactive timeline" sort of thing, though probably not starting all the way in 1789.
EDIT: Although.... it occurs to me that if the 12th amendment is never implemented, I could do what you want without eliminating any OTL candidates. Let's see how the 1796 and 1800 elections turn out.
