When we had the original referendum to Join the Common Market, it was purely for trade purposes only.  Since then the Common Market became the European Union and took more of a political bias.  Previous UK governments, especially Labour, have seeded power to the EU, without a mandate in the form of a referendum from the UK electorate.
When we went in, it should have been enshrined in the legislation that no powers could be seeded without this being agreed by a referendum.
I was in favour of us joining the Common Market and always thought I would feel this way.
I feel the EU want us out and are doing all they can to bring this about.
Come the referendum, I will now most likely vote for a full withdrawal.  YES the rest of Europe will have won.
