Here it is per capita: https://gist.github.com/BJTerry/d9392dc1d494cad052ef

Do you really think per capita works in this situation? It's not like your average citizen can pick up a surplus grenade launcher. Breaking down geo-politically would be more useful.

But grabbing per capita values from bjterry and going by party...

Senator Avg per Capita

Democrat $4.14 External (VI, PR, ..) $33.19 Independent $9.07 Republican $7.21

I think what might make more sense is to account for the location of large military bases.
