Biden has fallen some with independents which I follow very closely. His job approval among independents has fallen from 49% approve the first part of February down to 43% approve today. Overall, 56% of all adults viewed Biden favorably early Feb, down to 52% today. But that's no big thing, it can be chalked up to the normal ups and downs, the ebb of the flow.
Biden's problem may be the Democratic controlled congress. They're on the wrong side of the two most recent issues. Reparations, only 25% of all Americans support this, on adding justices to the SCOTUS, just 32% support that.
Now there's a huge difference in the perception of Democratic congressional delegation and Biden. The Democratic congressional critters are viewed favorably by 40% of all Americans vs. 52% favorable for Biden. The good news for the Democrats in congress is the Republicans in congress have a very low 34% favorable.
