If Georgia was "stolen" it was because Stacey Abrams, her organization, and the democrats as a whole have created a new "ground game" to take advantage of the mail-in voting system. The Republicans continued to rely on the traditional voting day mass turn out effort. Trump, and the two senate candidates have proven decisively that will no longer work.
Moreover, the more we delude ourselves in this conspiracy nonsense, the more elections we are going to lose. There was no sinister force, international manipulation, rogue algorithm, or traitorous Republican at work - just a party organization unable or unwilling to halt or adapt to a new voting reality, and a bunch of Trump supporters who voted in November who didn't yesterday. I think that can be set squarely at the feet of the right wing internet "news" outlets who have succeeded in convincing people their vote really doesn't count. In several key Trump counties Republican voting totals were 5-10% below November 3d. Abrams' organization, on the other hand, was busy even identifying likely Democrats who turned 18 over the last 60 days to make sure they requested and received a ballot. We better quit fantasizing and get to work in this new reality, or we really will continue to lose elections.
