When excluding a group from a calculation, rebasing involves dividing by the percentage of the sample that remains after the group is excluded. For example, if 40\% of people say they will vote Democrat and 20\% say they don’t know, we rebase by dividing the 40\% by 100\% – 20\%, which gives 40\% / 80\% = 50\%.
