One of the most powerful tools in the Karl Rove arsenal was a form of political Judo: take your opponent's strengths and turn them into vulnerabilities. For example, coming into the 2004 convention, Democrats had seen war hero John Kerry as pretty much unassailable on issues of patriotism and they made it a central theme of their event. Within a week or two, the Swift Boat Campaign made Kerry's service record an uncomfortable topic to discuss, flipping Kerry's advantage (that he had served in Vietnam and neither George W. Bush nor Dick Cheney had done so) on its head. This added the phrase, "Swiftboating," to the language of American politics.
