Is it possible to elect the presidential candidate by write-in vote?

That's a hypothetical question.

If the presidential candidate is de facto elected by write-in vote that collected enough electoral college votes to triumph over both Republican and Democrat presidential choices *against the overwhelming odds*, will the revolutionary election by the popular demand of the US citizenry be valid after registering as a "write-in" candidate?

For the record, I'm a registered Libertarian (former Independent) and I'm considering writing in Ron Paul (R) or Mike Gravel (D) if they are denied the nomination for president at the political conventions.

I currently reside in Utah where Mitt Romney is apparently very popular (his flip-flop on abortion, gun rights and other issues notwithstanding).

Most states have "official" write-in candidates.

To understand the process, states have three separate deadlines. The first deadline is to file as a candidate for the primary of an established party. For presidential candidates, this deadline only applies if there is a presidential primary. For president, there is a deadline for the established parties to name their electors.

The second deadline is for new parties and independent candidates to file petitions to be recognized on the ballot. For candidates for president, they must name the electors at the time that the petitons are filed. If there are enough signatures on the petitions, the candidates from these parties are also listed on the ballot.
