Did the UK population vote in support of the centre left, only to allow a centre right party to form a government? (Labour and the Lib Dems are centre left parties and the Conservatives represent the centre right). Looking at the results from that perspective, is the country getting the sort of government it asked for? Or is our system of democracy not representing the sentiment of the majority?
It seems clear from the above graph that PR (with several MPs from each Constituency) would likely have resulted in a Labour/LibDem coalition. (The inner ring of the graph indicates votes and the outer shows seats. More here.)
Of course, Interactive Democracy would largely avoid all of these types of issues, because the voters would have to be persuaded on each policy.
