A lot of these comments seem eerily similar to those saying that GA is fool’s gold.
Well would ya know it, Georgia wasn't "fool's gold"
People have a habit of assuming that the electoral map will remain static and that their party in particular won't lose any state that is at present considered relatively safe. Yes many blue avatars were wrong on the Democrat's prospects in Virginia and Georgia but red avatars are often wrong too. Prior to 2016 remember all those hot takes about the Democrats supposed rust belt firewall and how Wisconsin, Michigan and Pennsylvania were 'unwinnable' for the GOP?
It would help discussion a lot if people were more objective and less partisan in their psephological takes, but I very much doubt that will ever happen.
