Easy to see what happened in Georgia. Polling places closed, voting machines supplied with no power cords and dying off battery with four hour lines, voting machines in minority districts being left in the back, people showing up to vote and being told they already voted provisionally, people casting absentee ballots and them sitting uncounted at first.
The Secretary of State (running for gov) refusing to recuse himself.
This is stuff if plain as day for anyone with an unbiased set of eyes and a sense of right and wrong.
