From a few years living in DC, congressmen and Senators care about three things: Money, publicity and votes. The first two deliver the third. Pork (bits added to bill that affect something in their electorate) affects the second and third, and was probably delivered as the result of a contribution from a lobbyist who was retained by a corporate. I cannot recommend Larry Lessig's latest book enough to US voters.
