Nate’s whole post is worth a read, but as usual, he found an interesting way to graph it all. Here’s his map of some of the early/whispered candidates. I’m 90% sure that the blue is for people who’ve held some kind of executive office (i.e. governors/mayors/etc) and red is for people who’ve held some kind of legislative office (i.e. senators/congressmen). If I’m wrong though, please let me know!
I’m also surprised to see Crist’s circle so big… ugh. NOT. A. FAN.
