Can't blame the Barack Obama campaign for implementing Swift Boating defenses. Obama is particularly vulnerable because he doesn't have much of record in public service. So, unfamiliar voters pay attention to the Rev. Jeremiah Wright, and others who've made offensive statements. Obama tapped into a Democratic electorate eager for "change" to win the nomination. The rest of the electorate is waiting to hear what "change" means. Until then, voters will focus more on who Obama has hung out with, to search for clues, than on what he will propose for the country.
