Bolivia has a multi-party system, with numerous parties. During the first 23 years of renewed democracy beginning 1982, no one party succeeded in gaining power alone, and parties had to work with each other to form coalition governments. Since 2005, a single party has achieved a parliamentary majority.
Ahead of any national election a period of prohibition takes effect. This is with the intention of preventing inebriated nationals voting in error. Nationals are also forbidden from travelling around during the same period. This is to prevent voters from voting in more than one district. On polling day it is difficult to obtain a taxi or bus, due to the limitations placed upon travel and transport.
