It’s entirely possible that will happen, as it will at least give her a chance for a dry run at what being “President” might be like. Her being the nominee , however they would have to do it, would not in any way assure many—or even any, more votes than Joe would get-—so they lose no matter what.
“so they lose no matter what.”
They’re going to lose and I believe they’re already deep into a plan to rework their party. Then again they knew they were going to lose the 2020 election and that’s why they ran Joe. He had paid his dues and had enough dirt on enough people they couldn’t stop him running and Trump wasn’t going to lose until the Kung Flu allowed unverified mail-in ballots.
The scary thought is, what if Kamala is successful in appearing Presidential? That would really be another tragedy!
