In examining elections and government formation in Germany one can distinguish roughly three time periods: a ?formative? period lasting until about 1960, a period of stable two-and-a-half party competition with a limited number of coalition patterns in which the FDP played a crucial role, lasting from about 1960 to 1979, and a period beginning in about 1980 which has been characterized by party de-concentration and more complex coalition formation patterns. While the three periods generally apply to both the national and sub-national (Land) levels there are several important exceptions. For example, in terms of national government-formation patterns one could make the case that the second period did not end until 1998 when, with the inclusion of the Greens in the governing coalition, for the first time since 1960 a party other than the traditional three was represented in the federal government. In this paper we shall examine more closely elections and government formation in the latter two time periods and at both the national and sub-national levels in order to determine whether government formation patterns at one level have basically just been replicated at the other level and whether there has been a change over time in that regard. This will be followed by a closer look at the FDP’s ?hinge? role in coalition formation at the national and Land levels. Has the FDP’s role diminished over time? Have the Free Democrats formed coalitions with the same partners at the national and sub-national levels? Or have they formed governing coalitions in the L?nder that deviated from the national government in terms of party composition? Has the rise of the Greens adversely affected the FDP’s ?opportunity structure,? that is, have the Free Democrats been less often in a position to be the majority-maker (purely in terms of numbers) for either CDU/CSU or SPD? Thus, we will also briefly assess the Greens? potential role as a ?hinge? party and the relationship between that role and the formation of deviant/innovative coalitions at the Land level.
