Millions have bailed on cable TV over the last decade or so. Only old-schoolers think of cable viewing as a necessary default. I lived without cable TV for a couple of years, but in early ’19 I weakened and re-ordered it. Mainly for (a) the ability to watch Real Time with Bill Maher on Friday evening (it wasn’t showing up on HBO Now until Saturday) and (b) the MSNBC white noise that helps me write. Pathetic, huh? Frum’s point is that Biden voters are older, moderate and live better-regulated lives, and Bernie voters are more emotional, impulsive and fringe-minded. He’s correct.
