www.theguardian.com/environment/2016/jun/28/british-fishermen-warned-brexit-will-not-mean-greater-catches re fishing, because someone mentioned it earlier in the thread.
I live in Cornwall, which has already gone blue, and voted for Brexit, which really was Turkeys voting for Christmas. The EU has done so much to help Cornwall, when Westminster doesn't give a shit, but because of the fishing industry and a few other issues, people were persuaded to vote out. I also think a lot of young people feel generally hopeless, and so aren't motivated to vote.
Equally, I know a lot of Tory voters who voted Remain, because they actually looked at the issues and felt that for them personally, Remaining would help. Even the CLA were largely in favour of remain.
I think Tory supporters are motivated to get out and vote, whereas supporters of other parties currently aren't. Conservatives are also using fear to dissuade people from voting Corbyn- but we need to fear the Conservatives too. In areas of high unemployment, or with a lack of stable jobs, the mandatory 6 week wait for Universal Credit will see people starve. Currently, foodbanks are plugging the gap, but they won't be able to forever.
