You will find very little dispute on the Tory blogs with the idea that David Cameron should strengthen its anti-Lisbon line if the Treaty is ratified, including offering a retrospective referendum in Britain to ditch it. Where there is an internal debate, it is rather more about whether Britain should be in the European Union at all - and even that is a very one-sided debate with the "better off out" argument strongly in the ascendancy.
The anti-EU dominance of the Tory blogosphere
ConservativeHome is the main Conservative hub of online debate. It has been campaigning strongly for a stronger Eurosceptic line this weekend.
Founder and co-editor Tim Montgomerie favours Britain leaving the EU. Writing in the Fabian Review to preview our 'Who are the new Conservatives?' fringe, he writes "I support leaving the EU. I am a critic of the EU primarily because it has diluted democracy", though he told our Brighton fringe meeting that the political capital expended on leaving the EPP may well have sated the leadership's appetite for any further major Eurosceptic moves.
Montgomerie is the most influential voice in the Tory blogosphere - but his anti-EU position is fairly widely shared among the most prominent and popular Conservative blogs, and among the party grassroots more generally.
The Total Politics blogging poll offers a respected snapshot of which are the most popular political blogs. Here are the top 10 Conservative blogs - and a brief summary of where their authors stand on the EU.
1. Iain Dale - strongly Eurosceptic. Not (as far as I am aware) publicly in favour of Britain getting out. But blogged that he guessed (correctly) that vote-match software placed his EU views as closer to Ukip than the Tories, but was happy to vote for Dan Hannan.
2. Conservative Home - campaigning for a stronger anti-EU policy including retrospective scrapping of Lisbon if ratified. Founder and co-editor Tim Montgomerie favours withdrawal.
3. Dizzy Thinks - Favours withdrawal from EU, though appears to hold relatively moderately Eurosceptic by standards of this list.
4. Daniel Hannan MEP - leading "better off out" voice. Held stag night in Iceland to celebrate its refusal to join EU
5. Tory Bear - strongly Eurosceptic. [Position on UK membership not immediately clear]. UPDATE: "We have confirmation via twitter that TB favours EU withdrawal: "@torybear reply to "@nextleft Better off out!"
6. Archbishop Cranmer - very strongly Eurosceptic. Sounds in favour of UK non-membership (unconfirmed).
7. John Redwood MP - strongly Eurosceptic. Favours a trading relationship with EU partners.
8. Douglas Carswell MP - Hannan's co-author. Favours withdrawal from EU.
9. Letters from a Tory - Favours withdrawal from EU, and return to common market relationships.
10. Burning our Money - Favours withdrawal from EU to a free trade area.
(I welcome any clarifications of their precise position from those listed: this post is based on statements about EU issues and membership on their sites).
Does that mean British withdrawal is the coming argument in the Tory party?
The cycle of causation - how far the Tory blogs reflect the strength of Euroscepticism in party opinion, and how far they further bolster and strengthen it - can be debated.
What seems clear is that the party is much more anti-EU than it was in the 1990s, as the ConservativeHome survey of activists suggests.
As The Independent reported on Saturday:
Asked to outline Britain's ideal relationship with the EU, 39 per cent of Tory members believe it should pull out and set up a free trade deal with other European countries. A further 29 per cent say it should remain an EU member but seek a fundamental renegotiation of Britain's terms. Another 20 per cent want to repatriate some powers from Brussels. Only 9 per cent want to stay in the EU and oppose a further loss of sovereignty. In a sign of how far the Tories have shifted on Europe, a tiny 3 per cent of party members say Britain should play a full part in building an "ever closer union".
The pro-Europeans were always a more elite and less grassroots group than the sceptics. But the Ken Clarke generation of Tory pro-Europeans have very few obvious successors - and this does dramatise how they failed to mobilise and get organised as the right did. (Capturing the commanding heights of the Tory blogosphere has gone alongside something of a lock on constituency selections in recent years, which could prove particularly significant in future arguments).
So the anti-EU pressure on the party leadership will be amplified by the new prominence and salience of online politics in the party. The pragmatic arguments of more pro-European voices in Parliament and among business supporters will have very few public advocates in the party's public debates, especially online.
The leadership seems to have decided against a retrospective referendum, wants to avoid any substantive debate this week and is seeking some symbolic measure - perhaps a made-up referendum on a negotiating mandate to repatriate some powers.
But the main argument for compromise - that a post-ratification rejection could seriously damage Britain's relationships with EU partners and could pave the way to British withdrawal from full membership - may not get much of a hearing, when many high-profile voices actively want to see British withdrawal and may see a significant battle over Lisbon as just one skirmish in that wider war.
