I missed this. I would say the bit I've bolded is based on a fundamental misunderstanding of the post-2010 election situation. A Tory Government was basically inevitable after the 2010 election result, no matter what the LibDems did. The Tories didn't quite have a majority in the Commons, but they were so close as to make it virtually impossible to form a Government that wasn't Tory-lead. It was a choice between a minority Government and a coalition Government. And the LibDems evidently took the decision that a stable majority coalition Government, in which they could hopefully nullify some of the worst excesses of the Tory right, was a better option than a minority Tory-only Government. You can agree or disagree about whether that was the right decision - but it's wrong to blame the LibDems for putting the Tories in Downing Street. It was a combination of the voters and our distorted electoral system that did that.
