In a primary race where the differences between the two candidates are sometimes hard to discern, there were two vivid ones on display Sunday morning as Barack Obama did Meet the Press and Hillary Clinton did This Week in a town hall setting in Indiana. The first is temperamental. As she was with Bill O’Reilly, Clinton was funny, cracking jokes (this time about Rush Limbaugh), and looking and sounding like she is having fun. Barack Obama, as John points out, was dour, humorless, and emotionally remote. She was supposedly the one with the harsh and cold personality when this campaign started. Somewhere along the way things changed.

Second, their foreign policy perspectives are markedly different. From his point of view, threatening Iran is “George Bush foreign policy.” From hers, it’s making clear to our most menacing adversary that we mean business. Yes, they have merged views on Iraq (if you take them at their word), but the similarity ends there. She’s not exactly Scoop Jackson. But he is George McGovern (he 1970’s McGovern, not the more conservative one we have now). And this is a classic Democratic dilemma: McGovernites tend to prevail in primaries and Jacksonians in general elections.
