I give Cameron and Clegg 6 months...

or less before things start breaking down..

It is not like Cameron and his group are going to give an inch on anything that matter to Clegg - unless all he wanted was the paper-tiger title he got for the deal.

...there can be no divorce. There's Tory legislation going into the Queen's Speech for making Parliaments fixed-term, and requiring a 55% or 60% threshold for votes of no confidence.

Clegg can get in, but he can't get out. Brown's fate was sad, but Clegg's will be pathetic. Tainted by a Tory embrace he can't escape, he will be repudiated by his constituency committees, leaving him the leader of a party of all chiefs and no Indians. The 2015 election will destroy the LibDems.

Or is this a classic example of Uppity Third Party Smackdown?

...I would say "unwilling to lie and make bogus promises" -- on AV and PR. The Tories will say anything to talk Clegg out of his knickers, and have the party discipline to make it stick. If Labour sings "The Red Flag" and Conservatives sing "Land of Hope and Glory", then the LibDems should sing 'I'm Just a Girl Who Can't Say No" from Oklahoma.

And there's a deep, abiding, classist hatred of unions in the LibDem community, going back through the original Gang of Four, Tony Benn, the Winter of Discontent, Michael Foot, Clause IV, etc.... all the way to 1911. The typical LibDem lifer -- pre-1990, say -- is a progressive who doesn't want miners' dirty feet on his carpets. Or a non-mean Tory with an environmental streak. They're strongest in the West of England for a reason. No factories, nice scenery.

And even then you'd have needed the rest of the small fry -- SDLP, PC, SNP, for a stoplight coalition.

Frankly this result is the best that could happen to labour to reorganize and remember what they stood for before Tony Blair.

Let the Tories have this one while the Labour party regroups and removed the Blair elements from the party.
Unless there are tax increases on the wealthy(which will not occur under Tory rule), steep service cuts will occur and there will be a backlash.
