Representation in Congress

A historical question in US history since 1789:
 Is the primary concern of a representative the interests
of the whole nation or those of his/her constituency?

In traditional political science, two models of
representative function of Congress have been
offered:
 Trustee model – elected representatives are obligated
to act in accordance with their judgment as to what
policies are in the best interests of society
 Delegate model: elected reps are obligated to carry out
the wishes of those who elected them to office.
 Politico – a little bit of both, depending on the situation
Influences on Decision-Making


Later political research offers at least 3 theories why MoCs vote
the way they do:
Representational view
 Members want to get re-elected and therefore vote to please their
constituents
○ In what situations might this view be most likely?
○ What might make this view weak or less reliable?

Organizational view
 Members respond to cues provided by their fellow members; party is the
single most important of these cues, but interest groups/PACs may also
be important
○ In what situations might this view be most likely?
○ From which group inside Congress do members often take cues on how
to vote on bills? From which group outside of Congress?

Attitudinal view
 Position that ideology impacts a members vote; members are more
ideological in their thinking
 Because there are conflicting pressures, members are free to vote their
ideologies.
 On which type of issues will this be most strong? Most weak?

Supporting another member’s legislation in
exchange for future support
 The widest accepted origin is the old custom of neighbors assisting
each other with the moving of logs. If two neighbors had cut a lot of
timber which needed to be moved, it made more sense for them to
work together to roll the logs. In this way, it is similar to a barnraising where a neighbor comes and helps a family build their barn,
and, in turn, that family goes and returns the favor, helping him build
his.
 Special Interest Caucuses
 Informal groups based on shared interest
Interest Groups, Lobbyists and
Political Action Committees
 Research and Data
 Provide information to justify members’ positions on
legislation
 Persuade constituents to contact or pressure members
