Let's say, for sheer fantasy sake, that the Dems take both Georgia seats making it a 50/50 split in the Senate. Now let's imagine a vote comes up on a key clean energy bill in Congress. Which way do you think Manchin will vote? I have no doubts based on his voting record (nevermind that the GOP already had more than enough votes for a particular bill) for putting not one but two fossil fuel advocates as head of the EPA (the first, Scott Pruitt had to resign amid ethics scandals). And he's already come out as philosophically against "Green Energy". This man is really a corporate Republican in the disguise of a Democrat.
And you are overlooking the damage he can cause as a potential chair of the Energy and Natural Resources Committee. A quick look at what that committee does:

Coal production, distribution, and utilization; energy policy; energy regulation and policy; energy research and development; oil and gas production and distribution; solar energy systems......
This senator, who is most obviously beholden to his coal industry donors, is possibly going to be in a position to be the next Dr. No when it comes to Biden trying to get clean energy legislation passed. We can reference this conversation for later where I can say 'I told you so', or you will be saying the same to me. It's a moot point if the Dems don't take both Georgia seats as far as the chair position is concerned.....:shrug:
