That debate thang

Anybody else on itv.com as the thing ran last night notice how, maybe 10 minutes after the "best on the economy" poll appeared, Labour's %age started increasing, and at such a rate that the bar moved visibly on the screen, shifting from majority LD to majority Labour? Presuming the total number of votes was non-trivial, this would mean that an awful lot of people, who hadn't bothered to vote hitherto, suddenly decided they felt strongly enough to vote, simultaneously, and all for one party/leader.

Curious, really.
