When it comes to capturing votes, candidates do not always XX their speeches by state. Instead they may focus on particular areas of the country. Why? Because states often encompasses very different voting blocks. After searching the internet on my laptop computer, I came across this interesting map that was originally posted in the Boston Globe.

Here is the breakdown of each region:

Northeast Corridor - most densely populated, educated and affluent. Strongly Democratic.
Upper Coasts - well educated and affluent. More liberal than the Northeast Corridor, but also more fickle. Votes Democratic most of the time.
Farm Belt - smallest nonwhite population. Solidly Republican.
Big River - most closely contested region. Can go either way.
Appalachia - poorest and most rural. Starting voting Republican in 1980 and hasn’t changed since.
Sagebrush - named after the Sagebrush Rebellion of the 1970s (wanted the federal government to give more control of government owned land to state and local authorites) and includes parts of 17 states. This area is probably the worst for the Democrats.
Great Lakes - centered around Chicago. The urban areas tend to vote Democratic. The suburban areas are starting to lean that way as well.
Southern Comfort - average in education and income. Fifty years ago was solidly Democratic. Now solidly Republican.
Southern Lowlands - highest number of African American voters who vote Democratic. However, there are the same number of Republicans there as well. A swing area.
El Norte - highest number of Latinos and also includes Denver, Miami and Las Vegas. Usually Democratic but have voted in Republicans over the years.
