Gideon Rachman's blog: It looks as if Plan B for the Lisbon treaty may be in trouble already. It was obvious at the last EU summit that the idea was to proceed with ratification and then try to force the Irish to reconsider. Given the irritating inflexibility of the Irish constitution, that would mean a second referendum.

But a new poll commissioned by Open Europe suggests that a second referendum would result in an even bigger Irish No vote. Some EU leaders reckon that the Irish are bound to reconsider, if all the other 26 countries can be persuaded to ratify. But "isolate Ireland" looks like a dubious strategy. First, I'm not sure it's going to be that easy to secure ratification everywhere. Second, the new poll asks Irish voters how they would react if all the other countries were to ratify. Answer: they become even more stubborn.
