; their primary concern is to win elections so that their candidates can control important positions in state and local governments.
Interest groups are policy maximizers
; they offer citizens “a direct focused, and undiluted way of supporting advocacy on the issue they care most about."
- Interest groups are concerned about a single policy or at most a very limited nmber of policy
- areas, whereas the Democratic and Republican parties take position on a large
- number of social and economic issues.
