A Theory of Democratic Politics
6.1.1 - A COROLLARY
Presidents, as we saw in part 5.4, are usually appointed by some kind of majoritarian method. In presidential elections there are therefore forces operating which tend to reduce the number of parties. Now, since the same political parties usually appear in presidential elections and in elections for the legislature, the forces affecting the parties in presidential elections are likely to be relevant for the elections to the legislature as well. Presidentialism will thus have some tendency to reduce the number of parties generally.
