Here is the list of qualified candidates in the upcoming special election in Florida, for U.S. House, 13th district. Lucas Overby, a Libertarian candidate in that race, paid the filing fee of over $10,000 to be on the ballot. The Democratic nominee will be Alex Sink, and the Republican nominee will be chosen in a special primary. One write-in candidate, Michael Levinson, will have his write-ins counted.
Overby had tried to qualify with petitions in lieu of the filing fee, but his petition was 19 valid signatures short, so he had to pay the entire filing fee. The election will be March 11, 2014. Here is a newspaper story about the race. UPDATE: here is a news story about how the money was raised.
