The United States is unique in that for the vast majority of the time, the government is responsible for running and facilitating partisan primary elections. The rules that govern these primaries are important, and often have a significant impact on who votes in these elections, how their vote counts, and who gets represented.
Primary elections are often plagued with low and unrepresentative turnout. This can be fueled by a number of factors, including the timing of elections, whether they are partisan or non-partisan, and who is allowed to vote in them. There are several degrees of voter access to primary elections based on party identification.
