If President Ford had won in '76...

[MASHED POTATOES. VOTE!]

There would have probably been no President Reagan.

You don't think Reagan would have made a second play for the Presidency in 1980? He was considered a front runner as the next GOP nominee; He had just barely lost to Ford for the nomination. Ford would not have been able to run in 1980 and thus the GOP primaries would've been wide open.

Wait, how?  No one can be elected POTUS more than twice.

Ford served more than two years out of Nixon's term. Therefore he was allowed to run only once. See the Twenty-second Amendment.

Yes. From Vice Presidents who succeeded the Presidency after the Amendment was passed two were allowed to run more than twice: Truman (grandfathered, as he was President at the time it was passed) and LBJ (served less than two years out ot JFK's term). Ironically, none of them seek their own second terms.
