I genuinely thought all media would have used the name "Mike Pence" on the first mention. Simply "Pence" or "Mr. Pence" thereafter, sure.
Honestly, I was thinking more in conversation/social media and sometimes TV news/radio-- those last two with the possibility that if you're not tuned in at the beginning, you don't get it later on. The gender/name thing does come into play, I think, but yeah, if you were just/primarily seeking out articles on public figures, you'd probably come away knowing the first and last name, maybe throw in an initial.
