Three Questions to Get You Started
When you want to write about a candidate, the first thing I'd recommend is that you talk with someone who saw the candidate too. That conversation will tip you off to what was most interesting to you.
These questions might help jumpstart your writing. Don't think of them as an outline or a template. But if you can answer them, you will have the makings of a good write-up.
1. What did you learn about him or her as a person and as a candidate that you didn’t know as clearly before? (It might be a policy point, but typically, policy stuff can be learned in the papers or from a web site; you might get a view into values, character, priorities, etc.)
2. What was it precisely that she or he said or did that gave you that insight? (It could be certain words, an approach to answering a question, her or his manner of speaking, or something else.)
3. Why did you notice that particular quality of the candidate? This has to do with YOU -- your priorities and your values.
