The number of voters the Coalition is attempting to sway in the final days of the campaign varies widely, depending on how the targeted voters are defined. But the historical precedent for success to which commentators refer isn’t persuasive.
The party leaders’ final policy announcements and campaign appearances are about shoring up support among voters not yet fully “committed”, pulling “softly committed” voters away from other parties, and persuading those with no clear party preference.
These are the voters pollsters more properly categorise as “don’t knows”, or perhaps “won’t says”, rather than “undecided” – a category that can apply to those who have indicated a choice but aren’t certain about it.
