Not a 'game' at all, of course - rather the serious business of being responsible, mature public servants engaged in governing the country for the common good of all it's people.
So the endless question from a media that always seems most interested in looking for cracks and driving wedges: how on earth can two parties govern together whilst gearing up to campaign separately?
I think the answer is simple, so long as the people involved are mature, responsible and dedicated to providing the best possible public service. (Hmmm)
Each party has to be clear about it's current policies in the coalition context, which it will pursue up to the moment the government is dissolved, and it's future policies for when it is a majority party. It's not rocket science to be able to have two implementation plans within one consistent framework of principle.
The majority of the electorate surely understands that a manifesto is rarely implemented without constraints ... there are always constraints in the state of the nation that is handed over to the new government, and in the European and global economic and financial climates that prevail. Being in a coalition is another constraint, which requires perhaps even more negotiation and compromise than is usual ... and in these difficult times I believe the coalition has been a strength for the country, and not least because they have young, energetic leaders who have got things done in appalling financial circumstances.
On a related tack, it would be helpful if the media would sometimes ask positive constructive questions, instead of always trying to find fault and trip up. A question "why is there an apparent conflict between X and Y" will be answered along the lines of "there is no conflict" which leaves us none the wiser. Whereas a question "how are you going to achieve the promised x% or £yBn, and how will you measure that achievement" requires an answer of some positive substance.
Right now I think that if I could vote in 2015 for a coalition, then I would do so.
