Me, I've never taken my card before but did today obviously, the couple in front of me didn't have their cards but were clutching their driving licences for ID, the man behind had his card.
I asked the tellers if it was making a difference, they said too early to say I went at 8am.
Personally I think it will reduce turnout, school drop off parents won't call in if they don't have ID with them, the disorgansied will be excluded, people who don't know about it will be turned away and may never bother to vote again.
ITA, sledeghammer to crack a nut
