That's what the L.A. Times reports today.
Riordan was "stunned" when he learned from a television newscast that Schwarzenegger would challenge Gov. Gray Davis for the state's top post, according to one of Riordan's closest confidants.
The story seems to be based on a single anonymous adviser, so I wouldn't be so sure. Schwarzy (as the French call him) certainly hung a confidant or two out to dry, in order to create the surprise. And apologies to those bored by California politics—the recall is a story that just keeps on giving.
