This is referring to opinion polling in the pre-writ and election period. This kind of gets to the heart of the idea that if you do a poll on June 28, it will guide your work on July 2. Basically, it captures that you are paying in advance for the information you're going to be using during the writ period. This section specifically refers to public opinion polling, so it captures polls that are done immediately prior to a writ or pre-writ period, which will be used for the purposes of the writ or the pre-writ period. It captures those expenses.
