Concocted a nail-biter scenario, apparently.
President Ford upset by Governor Reagan at the '76 nominating contest.
Governor Carter does not run, Sen. Ted Kennedy does and wins the nomination.
Exceptionally close race, although Reagan's PV count steadily rose as the votes came in.
Everything came down to California, which very narrowly tilted to Reagan (3,986,067 to 3,974,597).
Gov. Ronald Reagan (R-CA)/Sen. Richard Schweiker (R/PA): 285 EV / 51% PVSen. Edward Kennedy (D-MA)/Sen. Henry M. Jackson (D-WA): 253 EV / 49% PV
It's possible for individual state projections to be incorrect. It happens every five simulations or so. Oddly enough, I've had elections flip in the final results screen hours after the state was called.
One time, I had Carter vs Ford come down to Ohio. Carter won it initially, but when I looked at the final results page, Ford was the winner of the election and Ohio had flipped.
