William Safire Blogs -- political phrases

I recently saw and heard Wm Safire on C-Span.

I would like his observations on the topic of Compound Movement Names, such as National Socialist or Compassionate Conservative.

Did Hitler start the genre and Karl Rove damage it beyond repair?

Are such phrases intentionally oxymoronic -- encompassing mutually-exclusive ends of the spectrum?

Thanks,
