I used a poker metaphor for the line of politicians raising the stakes on Iran.  The list included Senator Lindsey Graham (American Enterprise Institute), Representative Howard Berman (Center for Strategic & International Studies) and 
Joe Lieberman (Council on Foreign Relations).  After each talk, the pot grew.
Newt Gingrich 
weighed in on the Iranian threat at the Counter-terrorism Education Learning Lab (CELL).  His talk prompted a different pot, the kind that is stirred.  Newt's the rabid possum in the stew. Will he crawl out before it comes to a boil?
