There is no reason to expect we will know the result of the Presidential election on Tuesday night. Wendy Weiser of the Brennan Center and David Scott, deputy managing editor with the Associated Press, explain why.

The Supreme Court ruled this week to allow that counting to proceed in two key states, Pennsylvania and North Carolina. Election lawyer Ben Ginsberg has been following those cases.
