As for NPR listeners being conservative in this way, I won't argue, even if the word conservative is gratuitous here. Bob Edwards was an institution among the fair-trade morning-coffee set. And he's a virtuoso, even if he isn't writing the score. Everyone, liberal or conservative, should hesitate in a situation like that, to avoid blowing great talent just because some marketing guru suggested a "freshening up" of the program.
As long as we're on the subject: Wanna freshen up Morning Sedition? Theme music, for god's sake! Lose the f*cking "BAH-buh-bum-BAH-BAH-buh-dum-bum" that's meant to telegraph "Prepare to be told Important Things . . . " Who knew stale liberal earnestness and self-importance could be set to music.
