Why no Red Wave

First of all, understand that the Republicans and Democrats have a deal to keep the Senate 50-50 for the foreseeable future. The needle may move some either way, but it's not going far. If you were to look at the mail-in ballots, you'd likely see a split vote to achieve these ends. They would raise very little suspicion, unlike ballots marked straight (D). This is why you're seeing the split races in battleground states where the governor and representative delegations may be red, but the senators are blue. It's why KY elects a blue gov while keeping Rand Paul. It's why Warnock will beat Walker (face it -- they're both terrible candidates), yet Abrams gets pummeled (and rightfully so for being a race baiting grifter).

The only problem is that the senate no longer represents the individual states' interests but that of the MIC, and NGOs that perpetuate war and corruption. The senate will never vote to convict Biden even though the house will try to rightfully impeach him for high crimes and misdemeanors as related to Hunter's business dealings. It's why Trump will likely be indicted after the mid-terms for OMB and mean tweetz. The senate will likely confirm another wingbat for the USC to get the "right balance" but ultimately, they are going to do what they're going to do.

In a nutshell, you're going to get at least 2 years of gridlock, which may numb the pain, but ultimately, uniparty wants what its donors want, and they're going to get it regardless of what you want.
