6:27 PM - PST - Google has a map of the election returns here. At this moment, Romney has won 153 electoral votes to 123 for Obama. 270 electoral votes are needed to win.
These results are from the east but also include Texas; the west coast polls haven't yet closed, but will add a large number of electoral votes for Obama.
So as of right now, it is still too close to call.
