We have avoided mentioning it much here. Mainly because the arguments for an in/out referendum and a further fusing of the UK to to the EU isn't much of a real issue. Much like the Obama election , the result isn't in doubt.
In any referendum the nation would vote to stay in the EU, but to be allowed to have some minimal power restored. Probably the working time directive which we ignore anyway. Immigration would be the issue citizens would like to have control over, but that isn't going to happen. A slight move on citizens being able to claim benefits in any member country from day of arrival to maybe after 3 or 6 months or something might be as far as Brussels would be prepared to go.
The EU actually wants greater powers. A larger budget. Control of nation states finances. Its not going to start unraveling what it has already achieved just to placate a nation that isn't going to really leave anyway. Sure, the UK might become 'uncooperative.' But that's about it.
No poll has the UK wishing to leave the EU over treaty negotiation.
Not nearly enough of the population want to leave and no amount of huffing and puffing and pointing to idiotic banana rules or millions of new arrivals from Bulgaria will change the opinion polls much. So that's that.
For eurosceptics the Liberals are in love with the EU and would have the UK join the euro and become a proper , respectful, member state.
Labour is very keen on the EU and only pretends towards mild euroscepticism to retain its large working class vote share. Its unlikely to want to join the euro anytime soon, but wouldn't rule out joining at a later date.
Cameron's Tories, maybe as many as a third, are unhappy with Brussels so he will plot a course to try and win something from Brussels, possibly in exchange for agreeing to that 10 year increased budget that the EU wants.
UKIP, polling nicely, looking a better bet than the Liberals, but would be lucky to gain even 1 MP in an election. That gives them as much power and influence as the Greens. .. None.
Cameron is expected to say he would allow a referendum in 2015, AFTER the election. Good politics. Vote Dave and see if he'll really do it, or vote someone else and never, ever get the chance to vote on even mild reform.
I expect Miliband, if the election looks winnable for him, will avoid any commitment that he would have to break. The EU is an issue he wants the Tories to implode on and not something that he wants opening any divisions in his own ranks.
So, for Eurosceptics, the future is bleak. The EU is as weak and as divided and as poor, and as unpopular and impotent as its ever been. Yet still the majority favour being in. In Greece, with daily riots, racism, fascism and communism on the rise, real, actual poverty, record 27% national unemployment, no realistic prospects of recovery shackled to the Euro, the populace voted to stay in. Still vote to stay in. And they have a party, an extreme party to be sure, but a party that COULD take them out. The devil you know carried the day.
