This Atlanta Civic Circle article has details about the decision of an Administrative Law Judge to exclude all the petitioning presidential candidates in Georgia this year, as well as his decision rejecting the new law that should have let Jill Stein on the ballot because her party is on for president in at least twenty other states.
The Administrative Law Judge’s ruling is not the final word. The Secretary of State will decide.
An interesting detail near the end of the story quotes one particular voter, who says he had been planning to vote for Robert F. Kennedy, Jr., but now that Kennedy will not be on the Georgia ballot, that voter intends to vote for Donald Trump.
