As competitive elections have become more and more common around the w
orld since the early 1980s, there has been a corresponding increase in
public opinion research done for candidates and for political parties
in those elections. When the results of this survey research are made
available to scholars through national and international data banks,
social scientists can analyse the data in far more detail, illuminatin
g patterns of politics in their nations. Broadly, this enhances the de
mocratic process and demonstrates once again the importance of social
science research. As the essays in this volume make clear, accurate an
d useful opinion research can be done in countries which were until re
cently dictatorial, such as South Africa, while even in the oldest dem
ocracies, such as Great Britain, pollsters still have a good deal to l
earn in order to perfect their craft.
