Guess who’s not coming to dinner? The National Republican Congressional Committee and the National Republican Senatorial Committee abruptly told Sarah Palin on Saturday night that she would no longer be allowed to address the dinner. It was the second time that the committees snubbed Palin—they originally invited her to headline the event, but after she issued a press release announcing her appearance, they invited Newt Gingrich instead. Then, last week, she was invited again to speak—apparently “out of respect” for Gingrich. Now, Palin may skip the event altogether.
