You’re wrong and wrong. The GA election is UNLAWFUL for failing to follow state election laws. So the slate chosen by the cheaters in GA is as illegitimate as the elector slate presented by state legislators from the GOP for Trump electors. Both go to the Electoral college for presentation.
But the GA Runoff Election is already UNLAWFUL as well, because they sent out ballots to voters who did not vote in the special election for Senators, which violates state law stating only voters who voted in the special election that is being continued as a runoff may vote in the runoff.
The Georgia courts and the Georgia authorities don't seem to agree with you.
