It's one day to election day but it still feels far away. And it might night be over tomorrow night.

Those of us studying the national impact of tomorrow's midterms might have to wait for a while for the full picture to come into focus, writes David Wasserman at Cook Political Report:

A note of caution, however: by sunrise Wednesday morning, we still may not have a clear idea of just how many seats Republicans have won in the House. As one smart Democratic operative points out, between 10 and 20 percent of all competitive races could not be called on Election Night in both 2006 and 2008, and there were only about 60 competitive races in each of those elections. This year, with 100 races listed as competitive on our chart, the number of races left without checkmarks until later dates could easily run in the double digits.
