Evil Firefighters

Does anyone besides me think that the Firefighters Union may prove to be the single most important arrow in Kerry's quiver?

I've always thought that a firefighter is the purest example of a hero there is. They save lives while risking their own lives in the process but, unlike soldiers, they don't carry the negative baggage of occasionally having to kill people. When was the last time you saw an evil firefighter in a movie or TV show? Every other profession on the face of the Earth has been stigmatized by negative portrayals in the media. Every profession, that is, except firefighters.

How does Karl Rove demonize the firefighters who are criticizing Bush for exploiting 9/11?
