Several important changes have occurred in the European Union (EU) over the
course of the last decade. In particular, the Maastricht Treaty criteria f
or entry into the Economic and Monetary Union (EMU) brought economic auster
ity across the member states, in spite of high levels of unemployment in th
e region. At the same time an electoral shift resulted in parties of the le
ft holding government positions in 13 of 15 member states, a marked contras
t to the recent past. We examine if recent electoral fluctuations can be at
tributed to the traditional explanations of economic voting and anti-incumb
ency or if there is evidence of a fundamental shift in the electoral arena
following the passage of the Maastricht Treaty. Using pooled cross-sectiona
l data for the years 1983-1998, we find that for both EMU members and non-m
embers traditional forces help explain electoral outcomes, however an indic
ator for the squeeze of the post-Maastricht time period also plays a signif
icant role. While left parties have fared well in the post-Maastricht perio
d, the strong, negative effect of incumbency, persistent unemployment, and
an overall increase in electoral volatility make any conclusions of a left
turn in the member states of the EU premature. Rather, it is likely left pa
rties will find themselves faced with the difficult task of maintaining sup
port while abiding by the constraints imposed by the Maastricht Treaty.
