The Senate as a Social Network

Chris Wilson: “To find out how united or divided both Republicans and Democrats are in the current senate, I started with a simple concept: For every member, I calculated which other senators voted the same way at least 75 percent of the time. In effect, this organizes the senate as a mini-Facebook of 100 users, in which any given pair of senators are friends if they meet this 75-percent threshold. When visualized, the picture looks like the final stages of cell division when a Paramecium reproduces, in which a formerly unified body has nearly split into two distinct creatures.”
