I'm not so sure, in terms of their actual policies I hear the British Conservatives are pretty close to the US Democrats. They're cutting services for the poor, but to a level above that found in the US. That does typically show inclinations similar to those of US Republicans, but it could also reflect a view about the optimal end level of services similar to some Democrats. So I guess it depends on what it shows most often, and whether those inclinations are most informative for the purposes of understanding people (eg in this survey).
