Chris Matthews was smirking on Hardball tonight, discussing all the establishment-acceptable candidates (and ignoring the one who isn’t). Then NBC’s Chuck Todd broke the rules, right at the end, and said there’s a new question being asked in Iowa: “Who will place after Ron Paul? Will it be Giuliani and Thompson?” The other panelists giggled nervously. A shocked Matthews said, “That’s a sobering thought.” Sobering? Wait until the caucuses.
