Nate Silver chimes in by alluding to the classic discussion about how choropleth maps of the United States in a political context can distort a story. That’s because geographically large but sparsely populated western states skew the picture.

micah: Yeah, if the map everyone sees on Nov. 9 is covered in blue, doesn’t that make a difference?

clare.malone: I think it’s a reasonable goal for them to want to/try to win at least one unexpected state. A spot of blue in a sea of red can be a striking visual that people walk away with.

natesilver: So should they aim for states that are physically larger because they’re more impressive on the map?

clare.malone: Hah, yes.

clare.malone: No.

natesilver: Or not Alaska because it gets shrunken down?

harry: Is this a Mercator problem? I don’t know maps.
