Any person currently in --i- cannot vote. What is the blank word? Thanks.

prison?

minor

its jail

To determine the missing letter in the word --i-, we can follow the logic that any person currently in that category cannot vote.

Considering this, it seems that the blank word is "jail."

Since individuals who are in jail are typically not granted voting rights, it can be inferred that "jail" is the missing word in the given context.
