Why is the closed primary harmful to minor parties? a. minor party voters cannot vote in the major party direct primaries. c. minor party voters are able to vote in both primaries. b. minor party voters can choose which primary to vote in. d. minor party voters have their own primaries.

Hey there!

The correct answer to your question is option "C."

The closed primary is harmful to minor parties because minor party voters are able to vote in both primaries.
Minor part voters being able to vote in both primaries would be harmful since both primaries are different and in different opinions of course, one is better than the other.

Hope this helps you.
Have a great day!
