The great swath of the plains will have little voice -candidates will rarely even visit there- while the brilliant patches along the Eastern Seaboard, Great Lakes and Pacific Coast will pretty much be the chooser of the candidates.
Now compare this photo with the Electoral map of the US below and see which political spectrum would have the say on presidential elections. Blue states are Democrat-controlled, (in case you were not aware) and the Pacific Coast area sends us Nancy Pelosi along with Fortney "Pete" Stark, Maxine Waters, Jerry Brown and left-wing indoctrinating school curriculum.
The Great Lakes area gave us Obama, Reverend Wright, Rahm Emmanuel and Chicago-style politics. The Eastern Seaboard sent us Barney Frank, Carl Levin, Bernie Sanders, Al Sharpton and mushy RINOs such as Olympia Snowe, Susan Collins and Mitt Romney ( the latter being an excellent debater, however).
