The tactic being used today is familiar to those who have followed the activities of Karl Rove: Go directly after the other side’s strengths. Do not accept the truth or the obvious. Instead, make claims that cloud the issue. Some will believe you. Others will be confused. Your opponent’s strong point will be neutralized.
For example, in 2004, rather than just accepting the fact that Sen. John Kerry was a war hero, get people to say that he is not. Make such claims even if your own side is notoriously weak on the issue, even if your candidate worked hard not to go to Vietnam and spent months absent from his unit.
---Richard Clarke, Senior White House counterterrorism adviser in the Clinton and Bush administrations.
This is the tactic they use time and again. Count on seeing it a lot in this election and, sadly, in the comments section of this site.
