So in effect you are stating that all parties who go to the electorate with a specific manifesto should/must implement that manifesto if they then form a government. In effect that rules out any possibility of a Government being formed unless 1 party gets an overall majority. A manifesto cannot be written in stone as it's broadly based on circumstances and opportunity. In reality parties when elected should do their utmost to honour their promises ( reality unfortunately has shown us otherwise) but compromise will always be required when circumstances such as a coalition government or economic circumstances require a dilution of election promises.I think it is a slippery slope if you start encouraging parties to disregard their manifesto promises. You're voting for a package deal, and their policies on IW were part of the FG and FF package. I live in a city, if I vote for a party who has policies on rural Ireland, I'm giving tacit approval to them.
