Gov. Chris Christie may be at his best when he's saying, "No," and he got a chance to shine earlier this week, when he put the kibosh on a bill to expand medical marijuana in New Jersey. "I am done expanding the medical marijuana program. Under any circumstances," he said in that no-nonsense voice. The bill in question would introduce reciprocity to the program, so folks registered in Jersey could buy medical marijuana in any state with a similar program. "Here's what the advocates want,” the governor intoned. “They want legalization of marijuana in New Jersey. It will not happen on my watch. Ever."
