Pretty sure they're doing this to entice people to vote in the Georgia runoffs so Dems will control the Senate. "Vote for us and we can make this law."
This right here. It's literally this right here. So in other words, it's not pointless, it's political tactic. A good tactic to entice unlikely voters to vote Democrat.
Multiple reasons, depending on your level of cynicism. Least cynical is that there were competing priorities in the general and the current President was (is) an overall distraction from any policy discussions. Most cynical is that Dems don't actually like winning because it gives them somebody to blame. Both are corporatist parties that don't generally work for the majority of people. But, like I said, that's the cynical take!
