Aren't reporters supposed to want candidates to answer questions?

Apparently Marc Ambinder didn't get the memo:

09:29: Palin, again avoiding the question, decides to bring up drilling. Good for her, but the context is weird, and she's not explaining herself very well.

It's “good” for Palin to avoid the question?

More Ambinder:

09:20: E-mail bottleneck: I just got 5 fact-check e-mails from the Obama campaign...can't look at 'em all when they arrive at once.

Ok ... but what about the content? Was the Obama campaign right? Did Palin say something false? Isn't that a little more important than the logistical questions of when the Obama campaign clicked “Send” on their email?
