Although the title is something of a misnomer since this “map” is only of the House of Representatives. It is still so very colorful I couldn’t pass it up without bringing it to your attention, if you read this blog.

I find this map somewhat beautiful, though it might be touched up a little. Anyway, it is quite fascinating unless you have color blindness. If so, this might have been a wasted post. Sorry.
