Why should this be? One thought has been that there is a disease occurring in wetter areas that affects people's political thinking. If you get bit by a flying bug with that virus then you turn into a Democrat, otherwise you are naturally a Republican.
So, i went looking to see if anyone had done a study along that line and here it is ~ for Thailand, using a landsat satellite to provide sufficient detail so that you can relate mosquito densities to distance from various sorts of watercourses given different land types, e.g. forest, field, desert, swamp, etc.
It's possible that America's political landscape is literally divided into Red and Blue areas by biting insects, and quite possibly by our efforts to contain them. Mosquito abatement activities take place most vigorously in urban areas according to one of the studies referenced in this piece about landsat observatio, 'cause that's where the mosquitos are, and that's where the Democrats and Liberals are ~ cheek to jowl ~ mosquito bite to mosquito bite ~ day after grueling day.
Again, my thesis is that political preferences may be connected to the occurrence of biting insections (most likely mosquitos) and this correlation can be demonstrated by using landsat satellite technology to determine land/soil types, vegetation, presence of water, and existence of urbanization. Several studies have been done showing proof of concept.
If so, the best way to advance the interests of Conservatives and Republicans is to eradicate biting insects ~ AT ANY COST!
Hmmm, or people are naturally born Democrats, and the continual biting never lets them fully mature into Conservatives.
As one who frequently gets malaria (3 - 4 times a year), I find this information fascinating. Thanks.
