If not the Republican nominee---could Ron Paul be elected with an organized write-in vote?

With the advent of the internet,and popularity of Ron Paul, a write-in vote for him could be huge if organized...Past elections have produced a lot of votes for other canditates and this could be a time for the election of president in such a manner. Ron Paul is probably the only canditate that would get votes across party lines because of his stand on many issues. Many democrats would support him because of his stance on Iraq.Republicans and others don't like a lot of the canditates that would be on the ballot.
