Let's look at the full quote:
Casey does what he did against Rendel in the 2002 primary, and what he seems to be doing now, sitting bake and saying "I'm Bob Casey, Junior," and not running an aggressive campaign. Santorum does, starting in late August. The race is within the MOE by September 22
Casey began running an aggressive campaign in mid September, at the latest; I give him credit for learning from his mistakes of 2002.
Note that I
didn't predict a Santorum win even then and I also admitted, at around the same time, that I was undecided. I really only went into the Santorum column yesterday, though I was leaning in that direction. I could, up to that point, have switched.
Interestingly, Michael Schiavo was in town yesterday and criticised one of the Senate candidates,
Robert Casey, Junior. It made me see that what I disagree with with Santorum, I also disagree with Casey. What I agree with with Santorum, I disagree with Casey.
