The purpose of an election is form a Government. So it's simply not good enough for almost all the parties - FF, SF, AAA/PBP etc - to refuse to assist in forming a Government. The only way to get one's policies implemented is to be in Government. What's the point in seeking election if you have no intention of implementing (or trying to implement) any policies.
Is that really the purpose of an election? What we are really doing is electing public representatives.
After all, we don't just sack all opposition TDs the day after a Taoiseach is elected.
And we've had changes of government without elections (the change from FF-Labour to Rainbow Coalition in mid 1990s).
Representatives stood for election, on a platform and manifesto, seeking a mandate.
And when you stood for office and said, a vote for us is not a vote for coalition with X, people listened and voted on that basis.
What's the point of being in government if you have to jettison your manifesto and campaign promises?
I think it is in the long term national interests for elected representatives to stand by the promises they made seeking election. Anything else is seriously damaging to democracy.
Also, one can certainly argue the point that FF acting as a blocker to SF is more in the national interest than sorting out the next government ASAP.
I would rather see another election - and echoing your comments a more sensible outcome - than have politicians scramble for office without regard to their policies. And of course, I don't agree with a lot of the policies that are there. And there are several elected representatives who I would end up strangling if trapped in a lift with them.
But if people are going to elect people on those platforms then we have to hold the electorate and the elected representatives to that. Otherwise, we may as well just cast our votes at random.
