On September 16, Georgia filed this brief in Graham v Carr, n.d., 1:22cv-3613. This is the Libertarian Party case that challenges the law that lets individuals give unlimited amounts of campaign contributions to Democratic and Republican nominees for Governor and Lieutenant Governor, but caps donations from individuals to the nominees of other parties.
From the brief, it looks like the state has offered mostly procedural and standing objections.
YES, az, this looks like a job for the 14th Amendment, AND the state KNOWS it.
