I found a website that details some interesting statistics for your neighborhood.  This could even help you move into a neighborhood to find out who you have the best interests with.  The website neighboroo.com which displays a Google API map to show you different stats while pointing to the address you are researching.  My zip code came up as Very Republican with a population of 55,500 it has 71% Repubs, 30% Democrats, and 1% Independents.  While I went to vote today for early voting I felt like giving up because they all looked like Republicans (especially after looking at this site).  This neighboroo.com site also displays the air quality index which came up at two (I assume the two means good) for my area.
