Electoral reforms had profound political consequences for postcommunist Poland.
The majority system promoted the fall of communism, while later changes to the
electoral law helped the former communists to reclaim power. Despite the play for high
stakes and top priority given to electoral design by political actors, their manipulative
efforts were hardly rewarded. Although the political parties were ex ante seat
maximizers, they supported the electoral law that ex post would have given them the
most seats about as frequently as they supported the closest competitor of the above
mentioned one. The reasons for their miscalculations included a lack of methodological
expertise, unexpected shifts in voter preferences, transitionspecific poll biases, as well
as new entrants and coalitions that emerged in the period between the introduction of
the new electoral law and elections. No significant differences among the various kinds
of parties were found. The results do show that the effectiveness of manipulation has
strongly increased over time.
