Answer:
vote
Step-by-step explanation:
The tense of the sentence is present simple, as the action is happening on the regular basis. This means the verb stays the same in all forms, except in the third person singular. When the subject is the third singular person, we add ‘s’ or ‘es’ to the root of the verb. Here, it presents the option “votes”
However, in the sentence, the subject “voters” is in the plural third person. This means we don’t add anything to the verb and that it stays only in its root form – “vote”.
