It’s actually a good result for the Democrats but by them talking it up as if they were going to win, they made a tactical error. A quick check on Wikipedia shows the split between left and right in Georgia’s 6th has consistently been around the 65%-35% area. This time it was 52%-48%, reducing an 80k Republican majority to 10K.

The “Trump effect” just caused Republican support in a super-safe district to drop off a cliff and if (a big if) the same swing is replicated across the US… the GOP are f**ked. It’s a Pyrrhic victory.

Same sort of thing just happened in the UK General Election, where the left made huge gains on the right (but still lost). The difference being that the left were expected to lose badly, so their huge gain in power was seen as the victory it was.
