Parliament's Political and Constitutional Reform Select Committee, which I chair, has been doing just that by working over the past five years on a project with King's College London to develop several visions of what a democratic settlement for the United Kingdom could look like.
The argument for Scottish independence is one of heart over head. Study the detail, and you quickly realise that independence would involve a great unravelling of shared and highly integrated institutions, regulators and business relationships, which currently serve Scotland well.
At Clapham Junction, the atmosphere was tense. The mobile phone shops had their grills down, the bar across the road was closed. Large groups of teenagers were hanging around, hoods up. Commuters hurried home, including me...
The rise of Ukip, the vitriolic discussion over the relaxation of border controls relating to Romania and Bulgaria, the abolishment of the UKBA and now the problems at the Passport Office, show that immigration is, without doubt, an all-consuming issue for the public and one that is going to be at the front of voters' minds on and before 7 May 2015. However, the government, rather than shadow boxing with Ukip by continuing to make claims over a net migration figure they have no control over, should create a structure that ensures immigration is given its full attention. After all you can have as many silver bullet policies as you like, but without the gun to fire them you're never going to hit the target.
UK ministers always seem to preface what they say about the crisis in Gaza by acknowledging Israel's right to self defence against attack. I agree with them about that. Actually, the Palestinians have the right of self defence too. The point is that neither can credibly be invoked to justify the carnage that is unfolding.
The Tory Lie Machine is desperate to distract attention from the fact that they've raised taxes 24 times, and that tax and benefit changes since 2010 will leave the average household £974 a year worse off by the time of the next election - while giving millionaires a tax cut. But when they choose to lie about Labour's plans, we're going to call them out on it.
MPs' offices and the Parliamentary estate are funded by public money. It is only right that their spending is properly scrutinised. It is vital however that this scrutiny is properly informed. The media have a duty to report MPs' and Parliamentary spending responsibility. MPs' and the Parliamentary estate have a duty of care to their employees.
In a trio of uninspiring party leaders Ed Miliband holds a dubious honour. To the voting public he appears the least 'prime ministerial'. Having neglected to smoke cigars and throw up sporadic V for victory signs, he now finds himself languishing in the personality ratings.
Twenty councils, among them Green-led Brighton and Hove, asked the government for powers to put a levy on big supermarkets in their area. The money is to be used to support local communities damaged by the business practices of these giants... small businesses and cooperatives could again flower and grow in communities around the country.
Britain has benefited over many centuries from the amazing contributions of immigrants welcomed to our shores to build our biggest companies, sustain our NHS and win us Nobel prizes. And immigration will be even more important in future in a globalised economy. But it is because immigration is so important that it needs to be controlled and the impact of immigration needs to be fair for all.
The spotlight on the activities of the likes of Jimmy Savile and Rolf Harris, and current concerns about possible cover ups of establishment figures, must not distract us from our responsibility to ensure that today's child protection services function well.
I am particularly worried about the justice gap and the lack of action when it comes to violence against women. Not only have prosecutions and convictions fallen at a time when reported crimes are going up, there is a growing use of community resolutions which are just inappropriate for serious crimes. Much as the Home Office like to tell us this is OK, it isn't.
Miliband is certainly an intellectual full of ideas and a clever strategist. But Osborne has proved himself to be an equally powerful intellectual, better at gaming strategy. Labour could outwit Tory strategists. Instead of fielding Miliband in a 'presidential style' election, it could play the party instead as a collegium.
British Muslims are an extremely enterprising community. They contribute over £31billion to the UK economy every year. Over 100,000 British Muslims are civil servants, doctors, lawyers and accountants. In London alone, small businesses run by Muslims employ over 70,000 people... The majority of people view British Muslims as contributing well to our national way of life. Let us build on and strengthen that. While I'm fasting this weekend - when I'm hungry and thirsty - I will be thinking about what I can do to promote a more positive view of British Muslims - I think we should all do the same.
Reinvigorating one of the great offices of state will require a fresh look at how we exert global influence and how we identify early warning signs where countries with close links to the UK are heading towards trouble. Bangladesh is one such country and should be a high priority for Hammond.
Renationalisation. It is the rarest of policies, enjoying broad cross-voter support, whilst making economic sense. It works in Europe; it will save Britain money and ensure higher quality rail services. It's not a bold policy Ed, it should be obvious - promise to renationalise in 2015.
