Labour may be making promises it can’t keep (it's not like any other parties do that, is it?), but we stand to lose so much if Labour is not voted in: we could lose the NHS as we know it. We could lose the welfare state, which would mean that young, vulnerable families could face disastrous problems, whilst the rich get richer through tax cuts. It's happened in the US, and that’s what is likely to happen here.
If that sounds like something you don’t want, I’d recommend voting Labour on 12 December.
