If you are interested in what the political candidates think about charter schools, the Georgia Charter Schools Association has done Q&As with several candidates.
In a nutshell, candidates voiced support of charters and of fairer funding.
Here is the link to the candidates for governor. (Some notables are missing. Only Thurbert Baker responded from the Democratic field.)
Here is the link to the candidates for school chief. (Be forewarned that only Democratic candidates Beth Farokhi and Joe Martin responded.)
