This scenario was talked up for almost the past month: too tight to call on the numbers until ALL the votes were counted that were entitled to be counted. That's why we heard so much of a song and dance about state court decisions on what was submissable and for what period.
I think we are precisely where we were told we'd be. A landslide on the night would have been great, obvioulsy. But we were all told to prepare for this outcome.
Sit tight and watch the numbers ramp up for Biden in votes to be counted.
