Gay vote advertising

Yes or No for marriage equality?
That's your call and not my place to influence.
But ...
I'm staggered by the money being spent by those opposing or supporting the push for gay marriage. Each day there is a new leaflet in the letterbox; and some are quite nasty.
It's all wasted money because the bulk of the advertising started after most people had already voted. The advertising campaign was left too late.
In any case, I doubt that any of the advertising will significantly influence the outcome.
