Will Ukip remain if the vote is to stay?
I can't see it,they'll be waiting a long time for another referendum.
Also imo a large amount of the left will be swayed to vote 'stay' once they realise it will probably kill off Ukip.
If we vote out it will kill Cameron forcing his resignation so that's a plus for the snp and labour so there's different ways of looking at it in that respect.
