Not usual. Maria B is a free-market walking talking computer who’s knowledge of the stock market is hard to fake. She knows if another person isn’t knowledgeable of the issues at hand, and had graciously given Mrs. Palin her just due.
BTW, when you have a song/ode written about you by one of the Ramones (who turned Republican before he died), that’s saying something about the character of that person.
Joey Ramone was always conservative - mostly a Taft Republican in the style of beat author Jack Kerouac - but he loved Ronald Reagan and was angry at his bandmates for doing the song, “Bedtime for Bonzo”.
