Soup - apparently they will have some bloke telling everyone to go and vote now and then...
OK, in itself, it's not going to change voting apathy, but it is getting attention in the press, they are advertising the fact they going off air in advance, all of this will remind people to vote, and younger people are the ones who don't get out and vote, any way to reach them and remind them to vote is worth doing.
I've seen so much more stuff about the difference the 'non-voters' can make this time round, I don't remember there being this much push to get the electorate out in previous General Elections (am in my late 30s), it does seem to be coming from the Scottish referendum where there was general surprise about the percentage who voted. Getting the electorate out, however they vote, is important for democracy.
(I've also posted on a couple of threads where posters have said "there's no point me voting, it's a safe seat" that when you look at those seats, if all the "didn't bother to vote" people had got out and voted for the second place candidate - or sometimes the third - they would have won.)
