From the March 13 edition of CNN's Anderson Cooper 360:
JEFFERY LORD: Our friends at The Weekly Standard say that in 2010, the [Congressional Budget Office] said that 23 million would be enrolled through Obamacare by 2017. It's now 2017, and that number is 9.2 million, which means they were off by 14 million -- 48 percent. That kind of thing happens.
ANDERSON COOPER (HOST): Now what they say is that they didn't realize that first of all, Medicare -- that some of the states would opt out of the Medicare expansion.
LORD: Right, but that's my point, Anderson. We don't know what the weather is going to be. It's going to snow, but how much? I mean, we don't know. We don't trust weathermen, so why should we trust the CBO? Not that they're not good people, but this is the problem perpetually in Washington.
