One of the many jaw-dropping Palin clip’s from the Katie Couric interviewI notice that too. And figured it was a simple mistake. But as Sweeney notes, she did it again last night.
shows Palin saying that it doesn’t matter what caused global warming, what
matters is that we do something about it now. Now that’s bad enough as is, but
as Johnny Walker pointed out to me, she also says, “I’m not going to solely
blame all of man’s activities on changes in climate.” WTF?
I have no clue why she does this. I vaguely remember some discussion on the American Dialect Society list about a similar switch, but I can't remember the word it happened in, so search is useless. Maybe Young Eric has something to add.
Update: In the comments, Grant Barrett, of the American Dialect Society, reminds me that the ADS-L discussion was around 'exchange' verbs like exchange, swap, trade, etc. Still not sure if there is a connection.
