Open primaries promote engagement with political minorities  A major problem with general elections, specifically in countries such as the United States, United Kingdom and Canada which use Majoritarian Simple Plurality electoral systems, is that only two major parties (e.g. Democrats and Republicans) are in contention for power or in some cases representation, leaving those that have loyalties elsewhere feeling disenfranchised from a political system that does not take into account of their point of view.  Open Primaries counters this by allowing these voters a chance to vote for candidates of a major party that are closer to their own political persuasion, thus giving as many people as possible the opportunity to register their opinion on who will be their representative for the next term, ending disillusionment with predictable election results. This means that third party candidates may become serious candidates in elections when they pass the primary test. [1]  [1] Nielson, Susan, ‘Open Oregon’s primaries’, The Oregonian, 13 October 2008,
