I've tried to explain the negative Biden Approval Poll results here for weeks.
One of the largest factors are the Bernie Bots, and there are many, who think giving Biden Negative polls somehow will make it easier for Bernie to be more successful in 2024.
But keep this in mind- Even though the Bernie Bots are not satisfied with Biden- keeping his approval ratings down- does not mean that the low-approval ratings for Biden is going to favor REPUBLICANS in the Mid-Terms or 2024.
Because progressives are not swing voters! They either don't vote in protest (which is basically stupid and doesn't serve anyone but help get scoundrels like Donald Trump and other TRUMPARDS elected)- or vote for Democrats progressive or not!!
