The caging of Sarah Palin

TPM on the bizarre handling of Sarah Palin:

What’s really sobering is that the McCain campaign continues to block Palin from answering questions even though it’s now resulting in reams and reams of bad press for the McCain-Palin ticket. That suggests McCain advisers know that letting her answer even the most elementary questions in an uncontrolled environment is so dangerous that it’s worth weathering the current media drubbing they’re taking in order to prevent it from happening at all costs.

Of course there’s an alternative explanation: they’re worried that she will sound all too good, and will flip the ticket. I mean, she’s already on record as referring to a “Palin-McCain administration”….
No, no, no: I’m only joking. Really.
