If a politician tells you that "everybody is joining his team", then this is called a Bandwagon Propaganda.

An example of a Bandwagon technique is, "Most of the people are voting for this candidate. We should vote for him too."
Make sure you include all of the different ones such a s period or a comma and think of why you think it’s important like, “because if we didn’t have punctuation the sentences wouldn’t make sense and be scrambled” or anything else you can think of.
