I heard the original too but have been going along with the misquote. Either way, the excuse given that “he was just tired from campaigning” doesn’t fly. I’ve been very tired before too but would not make such a statement. Even if drunk too.
I hope you didn’t take me seriously. It isn’t really a pet peeve - it’s just something I noticed last week when I re-watched that clip after Sarah Palin posted her Greetings to All 57 States note on Facebook.
