Which do you feel is the best organization form for a political speech and why?

Justification

We aren’t looking for speeches that are only rants. But we also aren’t expecting pure philosophical or mathematical perfection. This is politics and in politics things are contested. But for that very reason you do need to give people reasons to agree with you and not simply insist. You need to justify the claims you make. We’ll be asking: are good reasons presented for agreeing with and believing the speech? Is evidence (facts, examples, references to authorities) brought forward when needed and used well? Are claims logical and sensible?

I’m going to guess #4 since that seems pretty logical.
