Good question.

Taegan Goddard:

Why did Katie Couric keep pressing John and Elizabeth Edwards on 60 Minutes last night about their decision to continue his presidential campaign when she didn't give up her job as host of the Today Show when her husband was diagnosed with cancer?

I've only seen the transcript, but assuming Couric's demeanor was a match for the prosecutorial tone of her words, I have a hunch she actually did the Edwards' a favor of sorts. She pushed them toward all the potential dark places and they came away reflecting that combination of courage, compassion and class that's becoming customary every time we see them.

And yeah, the fence is becoming a more uncomfortable place to roost all the time...
