Why do members of congress often support pork-barrel projects?
they are government-funded projects that directly benefit legislators' home districts or
states, so members of congress often support them to their constituents and the
businesses in their districts or states
they are underfunded projects that address social ills or issues, so members of
congress often support them because addressing and solving society's problems is a
major part of their job.
they are state-funded projects that contribute to the federal government, so members
of congress often support them because they are federal employees
they are privately funded projects sponsored by special-interest groups, so members
of congress often support them because they want to garner campaign donations from
those special-interest groups.
