Just because a senator gets a bunch of contributions from the defense industry does not mean necessarily that there is a quid pro quo, or even anything close. Many senators are naturally inclined toward a big military and so it just makes sense that defense contractors throw money their way. (It “makes sense” anyway, given our current system.) However, there is a pretty strong correlation between voting for bombing Syria and defense contributions as Wired explains.
Overall, political action committees and employees from defense and intelligence firms such as Lockheed Martin, Boeing, United Technologies, Honeywell International, and others ponied up $1,006,887 to the 17 members of the Senate Foreign Relations Committee who voted yes or no on the authorization Wednesday, according to an analysis by Maplight, the Berkeley-based nonprofit that performed the inquiry at WIRED’s request.
Committee members who voted to authorize what the resolution called a “limited” strike averaged $72,850 in defense campaign financing from the pot. Committee members who voted against the resolution averaged $39,770, according to the data.
