Repetition is a powerful rhetorical device often used in political speeches for several reasons.

1. Reinforcement of Message: Repeated words or phrases can help to emphasize the key points or messages that the speaker wants the audience to remember. This can make the speech more memorable and impactful.

2. Creation of Rhythm: Repetition can also create a rhythm or pattern in the speech, which can make it more engaging and persuasive. This can help to hold the audience's attention and make the speech more effective.

3. Lengthening of Speech: While it's not necessarily a primary goal, repetition can indeed be used to lengthen a speech, especially if the speaker has few ideas or points to present. However, this should be done carefully to avoid making the speech boring or repetitive.

4. Presentation of Arguments: Repetition can be used to present logical arguments in a clear and concise way. By repeating key points, the speaker can ensure that the audience fully understands their arguments. However, it's important to note that repetition alone does not make an argument unbiased.

Contrary to one of the points mentioned, repetition does not necessarily slow a speech down. In fact, when used effectively, it can enhance the pace and flow of the speech. However, excessive or unnecessary repetition can indeed make a speech monotonous and slow-paced. Therefore, like any rhetorical device, repetition should be used judiciously and effectively.
