Think about it

. . . here's an ad I'd run this weekend, if I was a Grit and seriously worried I was about to lose big:
Blank black screen. Type appears across screen as deep, urgent voice reads text:
'Foreign Minister Stockwell Day'
Screen darkens: relights on Liberal logo; bright woman's voice reads:
'On January 23, Vote Liberal.'
I figure that would be good for about a five-point swing all by itself.

Ah, yes, what a concept.
