Verified step by step guidance

1. Understand the types of primary elections: closed, open, blanket, and runoff primaries, each with different rules about voter participation.
2. Recall that a closed primary restricts voting to registered party members only, so voters must be affiliated with a party to participate.
3. Recognize that a runoff primary is a second election held if no candidate achieves a required threshold in the first primary, not related to voter party affiliation.
4. Know that a blanket primary allows voters to choose candidates from any party for different offices but may have restrictions on party affiliation.
5. Identify that an open primary allows any registered voter to participate regardless of their party affiliation, which matches the condition given in the problem.
