What you are reading is not something Mark Steyn wrote. It is what he said in an interview. If you have ever heard him speak off the cuff, you can recognize the style. I’ll cut him some slack for it not sounding like he spent hours finding just the right words.
And perhaps “Whose” was the transcriptionist missing “who has.” Or maybe not.
Thank you - I appreciate you cluing me in. I guess I didn’t recognize that style because I, unfortunately, don’t get to listen to Mark Steyn.
