The election is over. All the votes have been counted (well, almost all of them). It is time to take a look at the electoral map and draw some conclusions about how Barack Obama succeeded in securing a second term in the White House. The political leanings of the U.S. remain divided geographically. The Northeast, Great Lakes and West remain strongly Democratic, while the South and the Plains states continue to vote Republican. Meanwhile, the power of the "Big City Blues" -- Democratic voters concentrated in more populous areas -- was one of the biggest factors that helped Obama win the election.
