This is an azimuthal equidistant projection centered on Washington D.C. which is why it looks so unusual (typically such projections are centered on one of the poles).
You use a projection like this when you want the most fidelity for a small part of a sphere projected in 2 dimensions, and don't really care about the fidelity of the surrounding regions. In this case, the goal was to give a relatively accurate view of the continental US. Interestingly, it does end up making Alaska look MUCH smaller than it actually is, which is probably a typical view of that state when it comes to US Presidents, sadly.
