Certainly I can. For one thing, it was a debate and the subject was known beforehand, thus allowing Carter and his advisors to formulate his position.
Secondly, Carter wasn’t asked about his foreign policy expertise on national television virtually (or perhaps literally, I don’t recall) days after announcing his candidacy.
Third, as I said above, as candidate for president, Carter was in a position to define his administration’s approach to foreign policy - a position not available to a vice-presidential candidate.
And forth (and as I also said above), the newspaper question, as Palin rightly recognized, was a loaded question designed to make her look bad no matter her answer. If she’d said something like “The Anchorage Gazette” (don’t know if such a paper exists, but you get the idea), she’s have been lampooned for its lack of sophistication and expertise in reporting important issues, and if she’d said the NYT, the LA Times, the Washington Post, etc., she’d have been accused of thinking she could formulate something as serious and important as foreign policy based on nothing more substantial than reading newspapers - something any moron could do and which in no way qualified her for office.
Palin was being set up and she recognized it. She knew better than to take Couric’s questions at face value. The problem for her was that she wasn’t polished enough to fend them off with what we have come to know as customary skill.
ETA: With regard to my lust or lack thereof for Palin - said in jest or otherwise - I think she is strikingly good-looking, but not in a way that appeals to me. Plus her voice drives me nuts. Plus I haven’t been defending her - what I’ve been doing is pointing out liberal inaccuracies regarding her, and/or why liberal views of her experiences in the media are inaccurate.
