Doesn't it seem to you that 21-2-5 does apply since it is a federal office being sought?
And wasn't a notice of candidacy filed?
Why are you asking me? The judge said what the judge said.
If she was wrong then there will be grounds for appeal.
Laws are interpreted through precedence - if the question was raised before and it was determined in court that this particular law does not apply to primaries then that is how every judge in Georgia will interpret that law.
The judge cites specific prior precedence in saying that the SoS has no jurisdiction to interfere with political parties’ decisions on who they place on their primary ballots.
I think it is reasonable that it would apply but it seems Georgia case law disagrees with me.
