On legitimacy

The new Cameron-Clegg government will claim democratic legitimacy based on a combined 59.4% of the vote (36.46% Conservative, 23.03% Liberal Democrat).

That's one way of looking at it.

Of course, it's also true to say that not one single vote was cast for a Tory-Lib Dem coalition: there were no ballot papers with that option available, and no party manifesto explicitly offered it either.

0% of the vote looks a lot less legitimate than 59.4%.

What we don't know, and can't know, is how many people were "secretly" hoping for a Lib-Con coalition, while actually voting Tory, Lib Dem, Labour, or none of the above.
