I do not believe that the "administration" official who leaked the name is acutally a Bush supporter. "Administration" probably includes people in agencies like the State Dept. who do not like President Bush at all. I just don't believe that lefty reporters would go through all this mess to protect a conservative source.
The name was "leaked" (actually, it was her employment situation as in "CIA" that was disclosed) by administration officials (not in the WH, from what I can piece together) in order to answer the question "Why was Wilson of all people sent to Niger?", not out of retaliation against the Wilsons, as they allege.
There are big question marks if she was undercover or had been for quite some time, too.
I really hope we find out eventually because I am very intrigued and think the Wilsons and their cohorts in this story were up to no good, for this administration and therefore this country.
Yes, this is not Iran Contra. The media is strangely silent ...
