Wondering where things stood with the Wildrose-P.C. merger, there doesnt' seem to be anything official. And as always, Teh Wiki knows the score. Teh Wiki can be a pretty good news source before someone steps in to make the required edits.
As for the merger itself, I don't have any kind of opinion, but were I a Wildrose voter, I'd be pretty pissed off right now. The defectors are all damaged goods, lifelong running jokes, and will never amount to anything (see: MacKay, Peter).
