Voters will decide Tuesday whether to approve the proposed constitutional amendment, which would expand state influence over charter schools.
An analysis of campaign finance records by The Atlanta Journal-Constitution shows that pro-amendment groups have raised more than $2 million. Those groups include national school-choice advocates and for-profit charter school operators.
The newspaper's analysis shows that opponents have collected $123,243, mostly from public school officials.
Amendment supporters have mailers, billboards and a television ad campaign extolling educational choice.
Opponents are airing a radio ad in which The Rev. Joseph Lowery says the proposal would "resegregate our schools."
