The Republican vice presidential candidate is much like a self-propelled Furby. Someone says a slanderous thing in her hearing and she just repeats it mechanically until she gets another input. Do you know, someone mentioned reading the New York Times in her presence, and even though she clearly hasn't made a habit of doing this, she now repeatedly speaks of whatever article that person perused?

Considering the company she keeps, the things she says are not that great a surprise.
