I'm gonna watch the hearing on replay. I'll let you know what I think tomorrow though without even watching I suspect Roberts did fine and committed to nothing but being an impartial jurist. He's exceptionally smart and his extemporaneous speaking numbers are off the charts. A dangerous adversary and a magnificent ally in the courtroom.
Roberts ran circles around Biden. But that probably didn't require Roberts to use many of his vast number of highly honed synapses to do that. That is the only exchange I have watched so far. Joe tries so hard, but just doesn't have the tools.
