Why are current public opinion polls etc that relevant anyway? You've just had a general election in which an overwhelming majority was given to the side that promised to bring in a scheme providsing universal health coverage. That means the current administration has a mandate to push ahead with that.   

Fluctuations in public opinion are interesyting as indications of what might possibly happen next time there is an election, but that's all. The promise made to the electors on which they voted in November still stands as an obligation upon the administration.
