Editing Primary election (section)

=== Open primary ===
{{main|Open primaries in the United States}}In an "open primary", a registered voter may vote in any ''party primary'' regardless of his or her own party affiliation. Fourteen states{{emdash}}Alabama, Arkansas, Georgia, Hawaii, Michigan, Minnesota, Missouri, Montana, North Dakota, South Carolina, Texas, Vermont, Virginia, and Wisconsin{{emdash}}have open primaries.<ref name="State Primary Election Types" />

This system is sometimes criticized for increasing the ease with which voters can engage in [[party raiding]]. Raiding consists of voters of one party [[Crossover voting|crossing over]] and voting in the primary of another party, effectively allowing a party to choose a weak opponent in the election. An example of this can be seen in the 1998 Vermont senatorial primary with the nomination of [[Fred Tuttle]] as the Republican candidate in the general election.{{Citation needed|reason=Evidence that is this an example of raiding?|date=October 2017}}
