There really aren’t many differences in substance so far between this debate and the previous ones. Both candidates articulated the same foreign-policy views, and have restated what their seconds did the other night on domestic affairs.The difference is the pacing and tone. Bush is fired up and plays well in this setting. Perhaps he took a little nap this afternoon. Kerry is skillful, particularly in dropping in other issues at the end of his responses, but he also looks evasive. Sure, Bush isn’t answering every one of Kerry’s quick rips. That’s not how you judge these kinds of performances. So far, advantage president.
