Democrats would have likely netted between 4 and 7 seats, enough to flip the Senate. For starters, I'm assuming Loeffler wins the runoff. In your scenario, Perdue probably squeaked by with just over 50%, so Republicans would hold the Senate and Democrats would be far less motivated to turn out. However, they would likely flip GA in 2022, along with PA, WI and NC.
FL, OH and IA would be tossups, but I think Democrats would have picked up at least one, with their best bet being an open seat in OH or IA. Sweeping all three would be possible on a very good night.
Perdue would still go to a runoff with 49.9%.
Well, considering Dems won both seats after a Trump loss, I have to assume they would also win both seats after a Trump win. So the Senate is 50/50 and R-controlled through Pence unless James won in Michigan (he would need more that just a uniform swing).
If baffles me that this can be a serious take.
Republicans lost the first runoff in 20 years by 1% because they were demoralised after a stunning loss in a state they considered home turf, yet if Democrats had lost you think this wouldn't have affected turnout in a state everyone predicted they would lose?
Isn't is absolutely obvious that Black turnout would have collapsed after a Biden defeat? Just look at... every other runoff, including the one on the very same ballot but which the media didn't talk about as much?
