Another good description of Sarah Palin's strange grammar, from Heather Mac Donald at City Journal:

“Palin favors relative clauses that hang precariously at the end of sentences: ‘I am [interested in defending McCain’s health care plan] because he’s got a good health care plan that is detailed.’ Or: ‘I do take issue with some of the principle there with that redistribution of wealth principle that seems to be espoused by you.’ Her speech differs somewhat from the verbal knots into which George W.
