National Groups

A constellation of independent groups small and large surround each of the parties. These independent groups may focus on pushing a party in one ideological direction or another, electing candidates, training and building infrastructure or generating ideas.  Some groups are organized by constituency or issue. Another step removed from the parties (not shown below) are the many interest groups that tend to align with one or the other of them; examples include the National Rifle Association and Republicans or organized labor and the Democrats.
