Re: Wow, it's almost...
The big "issue" with P.R. that is that you can end up with either No government because they cannot get a majority or no decisions being made because no-one can get anything passed in Parliment.
I'd say that was a feature, not a bug. In general, if nobody can agree to pass a law, it probably mans that it's a law that doesn't need passing. You'll find that in countries led by "rainbow coalitions", the decisions that are actually important usually get passed, often after sensible compromise, and the ideologically led pogroms, like those of recent Tory governments, don't. Win-Win.
