First paragraph:
The way in which political parties organize is central to understanding their flexibility, strength, responsiveness and strategies of competition. In a multi-level setting, party organization encompasses the way in which political parties maintain integrated organizations across levels of government. This includes the way state and federal organizations are structurally integrated, the extent to which resources and services are shared through these linkages and the extent to which the levels of the party are considered to be the same party with shared goals and interests.

Last Paragraph:
The multidimensionality of vertical integration should prompt some theoretical refinement in research on multi-level parties. Vertical integration has different forms, these forms have different consequences, and they appear in different contexts. With new data, explanations regarding the causes and consequences of vertical integration can and should be specified for different forms of integration. How do we explain choices to remain structurally integrated or to provide resources and services? Under what institutional or societal conditions do shared goals emerge in the multi-level party? Secondly, the research agenda can and should now address the consequences of various forms of vertical integration, including party electoral performance.
