tbh the younger generation should get a bigger say as this is going to affect the most. However its the whinging richer than ever OAPs that turn out to vote on something which isn't going to affect them much. This Govt. has a policy of getting the young off the electoral register, 800k have disappeared thanks to recent registration changes. It may be good for them in a General Election, but they may regret that policy now.
Latest polling is showing a small shift to Brexit.

However I agree with the commentary; its got all the signs of the General Election and Scots referendums. People saying something 'trendy' to pollsters, then changing their minds in the final days when the economic uncertainty of a change hits them. Still expect a comfortable Remain vote, despite the young being disenfranchised.
