On protected sources

And in keeping with the media commentary theme, Jane Taber unveils the worst excuse for anonymity I've ever heard:

A month ago, a $500-a-head fundraiser to help John Baird’s re-election efforts noted that “in all likelihood a federal election will be called in 2011.”

In a few short weeks, however, that rhetoric has been ramped up considerably. A second email invitation sent around this week suggests the enemy is now at the gate.
...
A recipient of the invite, who asked to remain anonymous, noted the change in tone: “Two weeks ago it’s to help John prepare now it’s to come celebrate or vilify the nasty coalition.”

Which raises the question: who precisely is so afraid of not being invited to John Baird's fund-raisers as to need media protection?
