It is often discussed if a presidential candidate could lose his home state in the general election, or why he lost it, respectively.
But has it ever happened that a presidential candidate, who had won the nomination process, had lost his home state during the primaries?
It's an interesting question, but the only reason it happens in general elections is because the home state of the candidate leans heavily towards the other party. That isn't an issue in primaries so you'd be hard-pressed to find an example outside of fringe candidates.
