Most people don’t read the NR, and I’ll be willing to bet that most never even heard of it. So, it will actually have little negative effect, but it could show once again, that Trump is under attack by the republican establishment, which will increase support for him.
If NR represents the “Republican establishment,” why did the RNC throw them out of the next debate because of their opposition to Trump?
I stopped subscribing as my interests changed, and since WFB, Jr. died, didn't give it another thought.
As for NR in pop culture, in an early Woody Allen movie, he goes into a porn and/or newspaper shop, and NR's prominently hanging among the [gay?] porn mags.
Don't remember if that was before or after Allen was on Firing Line, let alone the movie.
