Weigel gives her fair treatment:
The original video, from Channel 7, really makes it look like Palin got a historical question she wasn’t expecting, and then flubbed it. The way she grits her teeth on the phrase “riding HIS HORSE THROUGH TOWN!” is agonizing, for all involved. And look, if someone asked me, on the spot, to explain exactly what happened during Paul Revere’s ride, I’d struggle a bit to access my elementary school memory banks. The twist, with Palin, is that she has a bona fide army of supporters who will sic themselves on anyone and anything that threatens to damage her image.
The difference is that she hasn’t yet retracted her error. Yes, as a quasi-POTUS candidate you are still a human with room for error. Own up to those errors. When was the last time Palin retracted one of her own comments?
