McKenna to leave Washington, seen as Liberal leadership contender

"I believe you would agree that the enormous value of a political appointment to this position is based on the ability to work intimately with the Canadian Government. It is this perception of closeness that provides a strong platform for the Canadian Ambassador to advance Canada's interest..."

Well, that didn't take long. Is Mr. McKenna your choice to lead the Liberals through their rebuilding phase? Or perhaps Mr. Tobin? Or Ms. Stronach?
Martin stepping down opens up the playing field quite a bit.
