In March, I posted this link to a
Google Maps application for the primary results by county for each state.
Since the maps show only one state at a time, I went to Photoshop and painstakingly put together a composite map, because I'm a nut. The fine-tuned version of that map
was here.
It laid out what the surrounding landscape looked like for the primaries in Pennsylvania, Indiana, North Carolina, West Virginia and Kentucky -- and the regional trends that crossed state borders already suggested that Obama "ha[d] a shot in Indiana, and especially North Carolina should be more do-able."
Well, three of those primary states are in now - PA, IN and NC. So it's time for an updated map.
Here's the small version - should give a nice feel for the overall patterns. But the details are pretty illegible, so to see the full-size map click on the picture (and when a new window opens, you probably will need to click the image there again to get it in real size).
