This is just a quick reference to an observation made over a number of years. The Tory Grimace is common to Conservatives. I'm sure you'll find it elsewhere, but nowhere is it found as often as on conservative faces. You see this expression when they imagine themselves making the "tough" decisions. What they forget, of course, is that the tough decisions are not always the right ones. You will often see this when they stubbornly stick to irrational choices in the face of overwhelming evidence that they are wrong.
