Some wags like to say that midterms don't usually turn on foreign policy. But two of the past three — 2002 and 2006 — certainly did. In those races, at least one of the two parties had something to say. In 2002, the GOP ran on scaring the hell out of everyone and by using tactics that morphed the faces of disabled veteran senators into Osama bin Laden's. In 2006, Democrats won seats based on voters' general antipathy to the Bush war record and their own pledge to work to withdraw troops from Iraq. 2014 should be a foreign policy election. But it isn't.
