"What's that old saying about sitting idly by while others' rights are trampled?"

Whose rights are being trampled? As the man said, it's all about who can command a majority in the house. And, if the figure that is being tossed about is correct, the Tories only had 37% of the popular vote. Sometimes the imperfect system works in your favour - in this instance, by allowing you to form a gov. with such a minority - and sometimes it works against you - in this cse, by (possibly) allowing the rest of the House the opportunity to organize themselves so as to take that gov. away from you.
