I'm sorry, but he can't win. Let's not be delusional here. If you look at LP results from the past decade, or more, they have roughly stayed the same more or less. Average LP vote for governor in 2012 was 2.05%, while in 2010 it was between 1-1.5% IIRC. There isn't going to be a magical increase. He's doesn't have any money and the media will completely shut him out.
I'd vote for Wyllie if I lived in Florida, but I think the LP's 40 year existence has proved beyond a doubt that third parties are not in any way, shape or form for any type of electoral success whatsoever. Losing an election while netting a mere few percentage points is not fun at all, it's actually pretty depressing. Third parties are not successful in the U.S., nor will they ever be.
Wyllie should primary Scott instead. He might get a little bit of attention if he was really aggressive, and his percentage would likely be at least ten-fold better than running in the general election.
The last Libertarian on a statewide ballot in Florida was Alexander Snitker. He won 0.46% of the vote. Definitively not worth it to run. That $42,000 he raised could have been spent on electing liberty Republicans instead. Most people had no idea he was even on the ballot until they went to vote.
