Voting for an MEP

When it comes to the issue of membership of the EU I fit into the lesser known third category. I am in favour of a European Union, just not this European Union. I am in favour of some kind of union that allows Europe to cooperate for the common good, but I am not in favour of the centralisation and complication of bureaucracy, or the removal of the powers of British people to govern themselves. So this leaves me with a conundrum. Do I vote for a good candidate (if I can work out which) that will strengthen an organisation which is vital in concept but devilish in the details, or do I choose a poor anti-EU candidate as an act of sabotage, hoping to destroy a form of organisation that is needed yet needs serious revising and simplification.
