Here's why:
* Transitive verbs require a direct object. The verb *acts* upon something or someone. For example: "She won the election." ("Election" is the direct object)
* Intransitive verbs do not require a direct object. They express a complete thought without needing to act on something.
In this sentence, "won election" is intransitive because it doesn't tell us what she *won* (although we can infer it). Similarly, "began fulfilling her campaign" is also intransitive because it doesn't tell us *what* she began fulfilling.
While we can understand the meaning, the sentence technically lacks direct objects for the verbs.
