Ezra Klein wonders why Palin is getting less coherent:
The fact that Palin's responses to questions are becoming increasingly incoherent rather than rapidly more polished is interesting. Rote memorization should have all but eliminated the overlay of nonsense in her answers by now. Matt Yglesias offers a decent hypothesis, saying, "It’s possible that all this cramming is causing Palin to become less coherent instead of just parrying questions she knows she doesn’t have good answers to, she’s trying to remember canned lines but it’s too much all at once to actually get right."
This is the person John McCain believes could take over as president in an instant and cope with three wars - in Afghanistan, Iraq and Pakistan - and a potential reprise of the Great Depression. Unbelievable.
