From Politco hardly a right leaning publication:
"That’s in part for reasons Biden refuses to accept: his capacity to do the job. The oldest president in history when he first took the oath, Biden will not be able to govern and campaign in the manner of previous incumbents. He simply does not have the capacity to do it, and his staff doesn’t trust him to even try, as they make clear by blocking him from the press. Biden’s bid will give new meaning to a Rose Garden campaign, and it requires accommodation to that unavoidable fact of life."
