Those are legitimate political arguments about voter suppression laws.
No one on the left claimed Kemp and Republicans stuffed ballot boxes or China hacked whatever.
The argument is based in facts. Many Republican controlled states, especially in the south, have historic issues with suppressing the votes of black and brown Americans.
You can argue over the extent to which this suppression still exists and how much it affects election outcomes.
But it is not even close to the same as arguing that the election was completely fraudulent because of real voter fraud, that the SOS or whatever bureaucrats should overstep their authority to throw it out.
