Unless it happened when I glanced away, up until this moment, 77 minutes into the 90-minute debate, John McCain has not once looked at Obama -- while listening to him, while addressing him, while disagreeing with him, while finding moments of accord.

This is distinctly strange -- if anyone else notices. Obama is acting as if this is a conversation; McCain, as if he cannot acknowledge the other party in the discussion.

More on non-body-language points tomorrow a.m.
