The subject in a sentence is the noun or pronoun that is doing or being something. The verb expresses the action that the subject is doing or being. I can be a simple subject, a complete subject and a compund subject.
A simple subject is only a noun or pronoun. A complete subject includes all the modifiers. A compound subject includes more than one subject--for example, when there are two people performing an action.
In this sentence, the candidates are the ones who are speaking, so the <u>simple subject</u> is "<em>candidates"</em> and the <u>complete subject</u> is "<em>Many of the candidates"</em>.
