Depending on the event, I like content to, obviously, be relevant to theme/topic.

Clear/clean delivery with good use of volume, rate, pitch.

In debate, I like to be able to understand with clarity.

For policy generally, I am looking for stock issues and how they uphold arguments. For PF and LD mostly how they present each of their cases and uphold their side. For speeches, it is mostly the delivery, the passion, and overall how well they are able to portray or convey their piece. For congress I am more or so looking for how many times someone speaks, this allows me to truly see how well they speak and how they present themselves.
