Lather, rinse, repeat
That's the sentence.
For the next eighteen months, every time the Bush Administration screws up, some version of that sentence (preferably a more pithy, clever, and catchy version) needs to come out of the mouth of every Democrat who gets near a microphone.
That's how you change the cultural consciousness.
Find a simple way of stating some version of the core of your message and repeat it over and over and over again until it becomes part of received wisdom.
It's also a good way to counter a talking point your opponents have successfully deployed.
Spend and spend Republicans, for example, needs to pass through the lips of Democrats every day, until "tax and spend Democrats" is effectively torpedoed.
