"Say if I was to write for a business newspaper and I was inexperienced with business still, would I sound really stupid, or what would be your advice on that, when the subject is specific but one that you are still somewhat inexperienced with?"

I'd say, "Write it from the perspective of a new buiness owner, or someone just starting out." The same thing applies to politics...if you're unsure or not very well versed in your topic...write it from the perspective of a beginner...a how-to article like "How you can become an advocate for this party", or title it with a question that you then answer in the article, like "What, exactly, has party x done for you?". Or even a factual column that should be easy to research. How this party came into being in 1776, or Party x legislative milestones in the last decade".

I hope this gives you some ideas.

Or maybe you can arrange to interview someone in the organization, and the article becomes a Q & A format. Easy cheesey, that one
