We can’t afford a Roll Call subscription, so we had to rely on HuffPo’s Jason Linkins to point out that Emily Heil and Elizabeth Brotherton reported that former Secretary of Defense Donald Rumsfeld failed to board a #42 Metrobus last week because the bus was too crowded. See Raw Story also for a funny recap. Despite reports that the architect of the Iraq war did have a SmarTrip card, it’s clear that Rummy isn’t a Metrobus veteran: he apparently gave up on waiting for another bus and just walked away. Any regular D.C. bus rider could tell you that, at least during rush hour, a packed bus is an indicator of bus bunching, and two or three other, nearly empty buses are sure to follow shortly.
