Which type of primary gives voters the most choice

The correct answer is an open primary.

Of the different types of primaries, the open primary allows the voters the most choice. A closed primary is the most restrictive type of primary and requires voters to be a registered voter of the party in which they are voting. An open primary is the opposite. It is the least restrictive and gives the voters the most choice. It allows voters to cross party lines and vote in any primary, regardless of their political affiliation.
