Simulations of changing levels of political knowledge among Danish voters in the 1971 and 2005 general elections reveal a strong impact on party choice. The analysis advances previous simulations from the American two-party system to a multiparty system by applying survey data from the Danish Election Studies. In both multiparty elections, the impact of information has significant consequences for party choice. In 1971, political knowledge seems to be the variable connecting class with party choice, whereas political knowledge seems to be the variable connecting issues with party choice in 2005. The information effects are greater than the effects observed in similar analyses of the American two-party system, thus suggesting a positive relationship between the number of parties and the impact of political knowledge. Finally, the analysis supports the notion that right-leaning parties tend to fare better if political knowledge increases.
