My point was that the press is already using it. The fact that Limbaugh is touting it as a line of attack won't make the line of attack new, or more effective. "Limbaugh said it" is going to add as much validity as "Baghdad Bob said it."
What is always in the back of my mind is that if Rush does something over and over on his show historically many other talkers or even tv guys will key in on it as well usually irregardless of what it is.
