"Good point" back at you.
Yeah, true .... if they could work together. My bet is that Labour and LD are closer natural bed-fellows than Tory and LD .... by a country mile.
If we define a coalition as the grouping that reflect a consensus of public opinion as reflected by votes, rather than a distinctly distorted representation of that as given by first past the post, then I guess the coalition that governed would be the first blend of parties that give an overall majority. It Lab+Tory could be formed, then fine. If not, Lab + LD. If not, as per 2010, Tory + LD.
But the system, in '97 and previous years, didn't permit that possibility because FPTP gave Labour a majority of seats, though demonstrably, not of votes. Not by a long way.
All of which leads back to my point - it was the system that put Blair in power, not the people's votes. If it was the latter, we'd have either had a coalition in 79, and 97, or a minority Tory (79) or Labour (97) government, not a one-party government with a large-ish (79) or huge (97) majority.
Oh, and I'm not suggesting that I support PR (or that I don't). Just that "the nation voted for Blair", as some type of president, is a bit misleading.
