Are There More "Extreme" Conservatives Moving Further to the Right?

I get the impression from news outlets (the one I listen to most being NPR) that the answer to this question is most definitely, "yes."  It seems to me, however, that the answer is only "yes," on a subtle disambiguation of the word "change," one which most listeners or readers of the media will not recognize.  Thus, I suggest that such media outlets are either yet again displaying their blind ignorance (likely) or engaged in more leftist sophistry (possible, but less likely I'd wager).

Distinguo between a so-called Cambridge change and (for lack of a better term) a real change.  To a rough approximation a Cambridge change for some x occurs when x changes though nothing intrinsic to x changes.  Example: I am to the right of the building.  I run to the left of the building.  The building changes from being to the left of me to being to the right of me, though, of course, the building does nothing nor has anything done to its structure.  If the building has changed by my movement, it's undergone a mere Cambridge change.

If there are more and more conservatives moving further and further to the right, I suggest that is true, but only if we take "moving" to be expressing a Cambridge change.  As progressives (who by nature are progressing) move further to the left, conservatives (who by nature resist change) are "moving" further to the right.  But while progressives are trying to foist upon states that gay "marriage" be recognized and sanctified, that suicide and euthanasia are Constitutional rights, that there is a right to free day care and a duty to pay for it, that it's the job of the government and not parents to feed children during summer vacations, that we should all agree that our ladies should be sent to military front lines on pain of being sexist...conservatives are plodding along with their old beliefs and political positions, ones with which Democrats not more than a decade or two ago would have agreed.
