Viggo Mortensen (aka Aragorn on Lord of the 9 Hour Rings) offers a kind of string theory on Sarah Palin's locution.
“I think it would be unwise to dismiss her because she is foolish and misinformed. People say there’s no way she will hold any significant office, in Congress, or as president. Don’t be so sure.
I notice she’s starting to sound relatively eloquent in that superficial way she has: ‘We gotta cut taxes and we can’t keep penalizing small business’—that same old litany.
She’s not saying anything significant but she’s stringing the words together.... do not underestimate her ability. She’s not going away.”
