True, although you could just tell the pollster that, rather than lying.
Since these opinion polls seem to affect the campaign significantly and turn out to be inaccurate at best, why not just add them to the list of behaviours that is already banned or strictly regulated during the election campaign?
It's already banned to try to influence people in the polling station, or to attempt to reveal how someone voted (exit polls notwithstanding), why not ban polling during the campaign?
