More from Tricky Rick?

Santorum calls for a debate with Casey, a full year before the general election (and well before Casey becomes the official candidate through the primary). Lively speculation on dailyKos about whether this indicates desperation; I think Santorum could be looking to (1) make a clear break with Bush policies now, so that he's not still running against them next year, and (2) demonstrate his superior public speaking skills (which have been remarked by many) and thence better qualification for the job. Casey unlikely to accept for those reasons and others, not to mention that there's still the technical involvement of Pennacchio and Sandals on the Dem side...

[Note: I also don't know what to make of the source linked by kos -- insider info, or pure fabrication? how is one to know?]
