Is the rot showing in to the coalition now?

No, but the rot is showing in the LibDem camp. For the first time EVER they are realising how easy is was to agree with the majority of the population when they didn't have to deliver. Now they are sharing the power they are seeing, just like parents do, that you cannot always do what the others want - sometimes it is necessary, for the overall good of all, to come up with something that is not popular. Those who defect or moan after less than a year in the job, aren't fit to represent the mes.
