On my yahoo! news feeder it says Palin's speech could "make or break the GOP's presidential hopes." Um, exactly what are they expecting to happen, for her to break down halfway through the speech, burst into tears, and run off the stage?
It's a speech pre-written for her by professional writers. It's on a teleprompter, so she doesn't even have to memorize anything. All she has to do is stand up there and read it without looking absolutely horrified.
It ain't rocket surgery.
