If fraud happens (again), then yes, Democrats will win both seats. If there's NO fraud, they'll lose one or both seats. There's no scenario where there's no fraud that they'll win both. Something interesting, though, the Democrat (don't them Democratic because they're not democratic) party elected officials are not united as the media leads us to believe. Sure, they're (almost) all against Trump and used everything in their arsenal to get rid of him in his first term, but that's only as far as the unity goes.
They lost 13-15 US House seats (with more to be called in the swing states), lost many state congress races, and even local races. Why? Simple, they wanted to:
-defund the police
-lock down small businesses for so long that'll it'll destroy 80% of the US economy
-raise taxes on EVERYONE, regardless of income
-socialism/communism replacing capitalism
-dismantling the 1st AND 2nd Amendments
-the Green New Deal
-advocate MORE domestic terrorism caused by groups like Antifa and BLM
-force people to buy government ran healthcare insurance while eliminating private insurance
-destroy the fracking, forcing millions of citizens to lose their jobs and watch them be shipped overseas
-repeal tax cuts
There's many more reasons, but you get the picture. Many Democrat officials are uncomfortable doing all this at once, while the AOC and Kommie Harris types want to shove it all down our throats when they take power, effectively making us (at least closer to) a third world country and China becomes the world's lone super power. We'd be at the mercy of these communist dictators, and I will bet those Democrats that are uncomfortable doing all this don't want ANY of that (can't say I blame them).
Bottom line on this is there's infighting within the Democrat party. I'll bet it's nasty, too. In addition to that, there was NO blue wave, but rather a MAGA wave. That's why I say with these two Senate races, the ONLY way the Democrats can win both seats is if there's fraud. From what it sounds like, they're already gearing up on it now as we speak with mail in ballots. The (faux) governor of Georgia, Stacy Abrams, is already advocating for people from out of state to come in, "register" as a citizen of Georgia, vote, then move back to their home state. Clear violation of the law, but the left is prepping to do it anyway. They're that power hungry and desperate to win that they have to resort to not only cheating but something that will land them in jail for a long time (if they get caught). That's today's Democrat party, people.
