The one that most springs to mind is their attitude to the PR system for the Scottish parliament. They're very keen on PR and they were very keen on the system used at that election. This is a mix of directly elected constituency MSPs, on a first-past-the-post system, and MSPs from regional lists to make up the proportionality.
Then, after the election, where it so happened that nearly all their MSPs (and Labour's) were constituency-elected, while most of the Conservative and SNP's were list-elected, they started denigrating the list MSPs in the most vitriolic terms, calling them second-class and "not real MSPs" and things like that.
I had quite a few more examples at one time, but I've managed to put them out of my mind.
