Farther to the right means farther alone.

Josh Marshall astutely notes that no longer do we hear the word "liberal" being spat as invective by the right, instead they've headed toward "socialist" or "socialism."

That would seem to indicate that the political ground has changed underneath their feet.

(Also, resorting to "socialist" seems something of the same overkill that it was in the campaign. You might create an environment where you can get talking heads to call certain Democrats "the liberal Congressman from...," but getting that reinforcing usage for "socialist" from legitimate media is going to be next to impossible.

It further isolates them in their rhetoric, makes them seem more out of touch, if they're the only ones shouting "Reds.")
