I don't know if I'd read too much into this, but what the hey. Here's a an email that recently landed in THE WEEKLY STANDARD inbox:
I want to invite you to what will be a great event coming up next week to help Congressman King prepare for his tough re-election battle against former Iowa First Lady Christie Vilsack.
New Jersey Governor Chris Christie will be in Iowa, and will be a special guest at a fundraiser honoring Congressman King. Iowa businessmen Denny Elwell and Bruce Rastetter are the co-hosts for the event, and the event will take place at Mr. Elwell's home in West Des Moines.
He's reiterated many times in the past that he's not planning on running. Now, I think he's just teasing everyone.
