The progressive left likes to use the term “zombie lies” to refer to untruths that are repeatedly debunked and yet remain endlessly parroted by the media. The phrase may or may not have been coined by blogger Duncan Black (aka atrios), who quipped, “No matter how hard we try to kill them, they keep coming back to eat our brains.”

Perhaps now we should start another meme: zombie bills. Or legislation that opponents believe to be dead but rises up from the grave. Exhibit A: ag-gag laws.

We covered last year’s attempts by Big Ag to pass several of these bills, which are designed to end undercover documentation of abuse on factory farms. And, as of last summer, it looked like the bills in Iowa, Florida, Minnesota, and New York were dead.
