From 538:
[The Clintons] have 17 field offices open in the six remaining primary states: seven in Oregon, five in Kentucky, four in West Virginia, one in Montana, and none in South Dakota or Puerto Rico. Obama, by contrast, has 44 field offices open: 17 in Oregon, 10 in West Virginia, seven in each of Kentucky and Montana, three in South Dakota, and none in Puerto Rico.
No wonder the appeal is now baldly racial.
