How will tomorrow change the Coalition?

Tomorrow there will be elections across the UK, but it is the AV referendum which will probably have the greatest effect on the Coalition.

The Conservatives support the No campaign and the Liberal Democrats support the Yes campaign. This means that however the votes goes tomorrow, one of the Coalition parties is going to be very disappointed with the result. This alone perhaps wouldn't be a great problem for the Coalition, but the tone of the campaign over the last few weeks has become increasingly bitter.

I don't think we are about to witness the imminent collapse of the Coalition (although I might be wrong), but I do think the previously convivial relationship between the two parties will change. I expect David Cameron and Nick Clegg will be working hard in the next few days to convince the country and their respective parties of the strength of the government.
