OPEN PRIMARY election is chosen when candidates are available from both the democratic and republican.
Answer: Option C
Step-by-step explanation:
Open Primary - An election that allows voters to decide on election day to which they want to vote. They will vote for candidates of only one party.
A blanket or "free love" primary could be a style of direct primary. Within the stall you mark a ballot that lists the candidates for nomination of all the parties, and so it gives chance to choose the Democratic candidate for one workplace and therefore the Republican candidate for one more.
