Bill Clinton let it be known beforehand that he wasn't happy making his speech on national security night -- preferring to talk about the economy and, hence, his legacy. You could tell. National security rated only passing mentions -- broad generalities when specifics were called for. This despite the fact that the Bush years have given us so many tragic specifics to remind the American people of. In contrast, Biden repeatedly, effectively, and with great detail made the case that on the key national security issues of our time -- including Afghanistan, Iraq, Iran, and Pakistan -- "McCain was wrong and Obama was right." It was a powerful indictment -- and effectively made the case that national security is actually John McCain's weakness.
