It's very hard for us LIb Dems and those who are desperate, let's face it, for full scale political reform to feel that, as it has been our first chance to use our position as a pivot party in 34 years that it will be our last chance to use our position as a pivot party for the next 24 years. The instinct therefore is to refuse to go into a coalition unless we get a promise of a referendum; unless we finally get what we were supposed to have got 13 years ago, if only Labour hadn't reneged on the deal.
Of course, that would be the best outcome. But it's a very hard ask of the Tory negotiating team and we should be looking to see what package of measures could still halt this stitch up between Labour and the Conservative in its track. It may be that one hung parliament isn't enough but two might be.
The eminent constitutionalist David Butler has oft suggested that transformational voting reform could take two hung parliaments to achieve, two consecutive hung parliaments.
Although we haven't had a hung parliament for a long time, that may not be the case in the future.
Over the last 50 years there has been a consistent decline in people voting for either Labour and Conservative, from 97% in 1951 culminating with less that two thirds of voters in the 2010 election. This means that hung parliaments are for more likely in the future.
Of course, the problem is that where the Prime Minister can, within a few parameters, can hold a General Election at a time of their choosing they will of course try and pick the point where a hung parliament is least likely.
But what would happen if the Conservatives agreed to fixed term parliaments? Well, the PM would no longer be able to manage the timing in their favour and hung parliaments would, on top of the psephological changes already working in favour of hung parliaments, again become more frequent.
The dynamics of election calling tactics would be changed forever.
I think we should go for as much as we can get; I think we need more that just fixed term parliaments but I also think that political reform that provides an environment to create that second hung parliament leading to electoral reform is quite a prize and we should be wary of walking away from it.
I worry that all those who want electoral reform seem to be equating the Liberal Democrats raison d'etre with voting reform; while important we are not a one policy party. It is unlikely however, that without a healthy vibrant Liberal Democrats that we will ever get voting reform as Labour's commitment to it comes and goes in line with their proximity to power. So, do not make the Liberal Democrats succeed or fall on this one negotiation and this one election.
A coalition with the Tories, would allow us to reign in the worst excesses of conservatism, in all sorts of policy areas including political reform and if set up for a relatively long period help create the economic stability that this country needs. Making a coalition work, on Britain's journey towards proportional representation, is as important as the concessions that we win from that coalition.
Coalition governments are risky in many other ways for support parties, whether or not their in it for constitutional reform, but could bring enormous benefits to the people of the United Kingdom; I'm not normally the type to be patient but I think that all of us who want a proportional voting system should look to the long game and not throw out the baby with the bathwater.
