The invisible chief?

Linda Greenhouse has an article about how only 28% of Americans can identify John Roberts as the Chief Justice of the US Supreme Court -- even when fed Roberts, John Paul Stevens, Harry Reid, and Thurgood Marshall in a multiple choice question.  Fifty-three percent simply didn't know; 28% got it right; the rest (20%) got it wrong.  (Though, depending on how you count the votes, maybe everybody got it right.)

Greenhouse finds this surprising.  I don't.  But it reminded me of a recent snippet I read from Tony Blair's new memoir:

The single hardest thing for a practising politician to understand is that most people, most of the time, don’t give politics a first thought all day long. Or if they do, it is with a sigh...., before going back to worrying about the kids, the parents, the mortgage, the boss, their friends, their weight, their health, sex and rock ‘n’ roll..... 

This is doubly true for the politics of the Supreme Court, I would think.
