While I understand the
instinct to regard the strength
of two party politics
of 1950 - 51, or the broader 1945 - 70 period, as the natural order
of things, there is as much or more reason to think that the type
of more pluralist party system which has arisen since 1974 (despite the systemic barriers to it) is here to say and the
idea that any 3 + party system is always a
death match to find out which the two «real» parties will be is somewhat ahistoric and unlikely.
