Bush's Big-Lie-by-Implication, that Iraq was involved in 9/11, is now so deeply ingrained that even Chris Matthews, who for several decades (as a congressional aide to the Speaker of the House, a TV pundit, a columnist, and the author of several books) has earned a living based on the presumption that he knows what the hell is going on in the world. Here he is talking to Ann Coulter on his shown on Monday night:

COULTER: ...North Korea is different from Iraq. That isn’t -- the 9/11 terrorists didn’t come out of that region.
       
MATTHEWS: That region. But they came out of Iraq.
       
COULTER: No, they came out of the Middle East.

Even Coulter (who presumably hangs out with many of Big Lie's most prominent promulgators) seems to know better.
