In fairness, the Dem Establishment is in a tough spot: they have a President who has led the country onto the brink of full recession, into skyrocketing inflation, through a disastrous/failed CV19 response, and has us positioned as a feeble/flailing nation on the world stage. A huge war continues in Asia and tensions with China and N Korea are high. Biden is, by any measure, suffering from senile dementia. Yet, they don't have a single answer, nor a viable, competent successor for the next election.
This is a desperation move, over a dumbass aged offense that should carry no more penalty than a slap on the wrist. We are freeing violent offenders and letting Fentanyl pour across the southern border, despite it now being the single largest killer of younger adults.
It will backfire, and it could get really nasty. Pulling this junk and attempting to martyr Trump (who I do not really care for) could result in costly and devisive protests, violence, and potentially galvanize groups already sitting on a powder keg and armed to the teeth.
Here's an idea: come up with a plan to get the country back on track and present a 2024 candidate who doesn't poop his pants. Then, you don't have to worry about Trump. The Right will be forced to produce a better candidate, and we will all be better off.
