Soul Politics has already had most of the thoughts I was going to have, excellent post and analysis of some of the key issues. So I'll save you time and not write anything.
Meanwhile the BBC has produced an election night party pack, if you were planning on staying up, and had any friends. I really hope the BBC gets its act together this evening, the last results show I watched on there was dreadful. I imagine Twitter will be a much better way of keeping up with what's really going on, but it doesn't have a decent Swingometer.
