The Democrats did pick up 1 US House seat in Georgia, and came within 900 votes of picking up a second. It just means we have to work harder next time, and allow more time for demographics to work in our favor. Note the population change by county size . Large counties are growing, small counties are shrinking or not growing as fast as the state as a whole (8.85% since 2010).
The New York Times made a nice graph of margin of victory in 2018 vs how rural/urban the House district was. The hyphenated categories, like "rural-suburban" are because congressional districts often cover two types of population density. The correlation of democratic to population density is very obvious:
By the way, Tuesday Dec. 4th will *still* be Election Day in Georgia. Two of the statewide offices, Secretary of State and one of the Public Service Commission seats. None of the candidates polled over 50% in November, because the Libertarian candidate got about 2%. So we have a runoff. The significance of Secretary of State is that is the office the voter-supressing governor-elect Brian Kemp held previously. A democrat taking his office would be sweet revenge.
I already did my early voting this week, along with at least 400,000 other people in GA. The result will depend on who has more enthusiasm, because special elections usually have much lower turnout.
We have that in Georgia too. In a normal ballot, you get some drop-off in votes cast as you go down the list, because some people haven't investigated the lesser offices, or are in a hurry. This time, the lieutenant governor showed 100,000 missing votes, but *only* on the machine tally. The mail-in votes show no such drop-off, which indicates is was not disinterest in that race. Georgia has no paper trail for our election machines, so we don't have a way to verify how many votes were actually cast. One thing you can do is inspect the software and test the machines, but the Secretary of State, who oversees elections, seems disinterested in doing that. Here's a comparison of votes this year by office vs past years, relative to the governor's vote, which is first on the ballot:
