From the NYT: when things go bad, just claim that your message is not being sent correctly. Felipe Calderón perhaps learned that from George W. Bush and now Barack Obama as well. It's not that people don't like your policies, it's that they don't understand them well enough:
The administration of President Felipe Calderón has not shown signs of shifting tactics. Rather, his aides believe the problem is that his message — that the violence is a sign that progress is being made — has not been delivered well. There has been a shake-up in his communication staff to improve it.
Shoot your messenger, and all will be well.
