Looks like things could get awkward at the Republican National Convention. Sarah Palin said Monday night that New Jersey Gov. Chris Christie had “gotten his panties in a wad” in a “rookie mistake” when Christie called Newt Gingrich “an embarrassment.” “Poor Chris,” Palin said on Fox Business News. Palin said Christie, a first-term governor, had yet to learn that reporters will try to “goad” him into making comments that will end up playing into the hands of Democrats if Gingrich is the nominee. Palin has not endorsed any candidate yet, although her husband, Todd has endorsed Gingrich. Christie is one of the Republican party’s best-known tough talkers, but his spokesman said Tuesday that the governor will not be responding to Palin’s comments.
