At the end of each month, The BFD will put up a new poll with the same question so that we can track changes in voters’ preferences in the lead up to the election on September 19th.
Each month we will analyse the previous month’s results so that we can see which parties are gaining, losing or maintaining support in the lead up to election day.
If National changes leader part way through the year, for example, we will be able to tell you if that has affected support for the National party or not. Alternatively, if they do not change their leader we will be able to see if the voters that were expecting a leadership change remove their support for National as the election date gets closer.
