I’ll give you that polls have been known to be completely wrong. Like this one posted November 7th 2016:
That being said, you are the only person I know that is totally satisfied with Biden. I do realize that is a sample size of 1, but the litmus test is that there are many Democrat mega donors and delegates worried about Biden being the nominee. You are also making a huge assumption Trump is going to be in a Georgia jail & penniless. Remember that he has to be proven guilty beyond a reasonable doubt by twelve jurors.
But we’re speculating…that’s why we have elections. We’ll know the truth in 12 short months.
Edit: Also I don’t know about the GOP fatigue. I’m pretty fired up to see Biden (or Hillary, Kamala, Michelle, Gavan if it’s them) voted out.
