LDV Poll: Should Lib Dems Stir Shit on EU?

Lib Dem Voice are running a poll, currently pretty evenly poised, on whether Lib Dems should back a referendum as The Telegraph suggest. Stephen Tall asks:

What do you think? Should the Lib Dems support the
demands for a referendum - after all, we were the only mainstream party to call for one to validate the Maastricht Treaty - or would this simply be pandering to a Eurosceptic media, exploiting issues too technical to be decided by a
simple Yes/No vote?

I tend to agree with reasonable comments from tinter and the reliable Lawrence Boyce.

As a party which locally will call for a referendum at the drop of a hat - but not provide them if in power - the Lib Dem high ups should heed their remarks. Mountjoy (here today doing the old 2+2=5 shuffle on jobs, benefits and gast arbeiters) unintentionally says it all in a comment at LDV - it would be political opportunism of the worst kind:

Yes, because Brown is seriously isolated on this issue now that 120 of his MPs have called for a referendum.

So nothing to do with the merits of the case? Just naked opportunism? This is why I fully expect it to appear all over the place in Focus newsletters in the fairly near future! Surprise me please.

Of course a referendum could be won on the merits if there is an honest debate. Being as this one is 75% electoral opportunism and at most 25% substance then LOL are dubious that could happen.

Might yet be persuaded. So let's have a supplementary question. If there were a referendum should Lib Dems (and indeed other opportunist opponents) campaign against the government? If not, what?
