As long as Hunt stays above 4.5%, this one looks to be going to a runoff
If history is any indication, it's unlikely Hunt will do that. The last libertarian to run was an NAACP county chair and finished with 4%. It was the only time a libertarian finished with over 100,000 votes in a state-wide Georgia race.
3-4% is more realistic for libertarians in Georgia governors races, although Hunt has been a decent candidate as far as Ls go.
It's probably about 50/50 the governor's race goes to a runoff though.
