The problem...
is that the political scale has been "redefined" a good distance to the left. For example, a Republican who supported nationalizing the health care system would nowadays be defined as a "moderate." Come to that, a "moderate" Republican seems to be one that has no significant differences with a Democrat.
Of course, all Democrats believe themselves to be "moderate." There are no "socialists" or "leftists" to be found, despite the commonality of goals and methods. So not only has the scale shifted to the left, it doesn't even seem to have a left end any more.
