I like this take.

Did ML McConnell outfox himself? It may be that postponing witnesses gave the House Managers the golden opportunity to spend days, uninterrupted, presenting an organized & compelling case. Rarely are Senators forces to spend such time focusing on an extensive briefing.

McConnell created a content vacuum, and Schiff has taken full advantage of it.
