It's an extraordinary fact of the campaign underway that three of the four candidates for president and vice president have sons who already have or are soon deploying for military service in Iraq.
They say this is a foreign war that has touched only the enlisted, with most Americans disconnected from any personal investment in a conflict that has raged for nearly six years. But it has touched most of the families with eyes on the White House.

Private Fist Class Track Palin, son of the Republican vice presidential nominee, enlisted in the Army National Guard a year ago, on, yes, the anniversary of the Sept. 11. attacks, which, as everyone knows, have nothing to do with Iraq. (He is pictured right in an AP photo by Rex Arbogast from the Republican convention.)
And, as Gov. Sarah Palin, the GOP's vice presidential nominee, announced at the Republican National Convention last week: "One week from tomorrow, Sept. 11, he'll deploy to Iraq with the Army infantry in the service of his country.''
Democratic vice presidential nominee Joe Biden's son, Beau Biden, a captain in the Army National Guard, will deploy to Iraq in an administrative role. This is his first deployment to Iraq. He joined the Guard in 2003. An attorney, he will be deployed for a year, part of his brigade's administrative staff, providing counsel as a JAG. (The Biden's are pictured at the Democratic convention in an AFP photo by Paul Richards.)

Marine Lance. Cpl. Jimmy McCain has been there already.
In a family with a legacy of service starting at the U.S. Naval Academy - his older brother, John S. McCain IV, is a midshipman - the Marine McCain's six-month deployment came and went without notice, because his father, John S. McCain III, a retired Navy captain, has not spoken about it publicly during his campaign for president. (Jimmy McCain is pictured below arriving in Minneapolis for his father's convention in an AP photo by Stephan Savoia.)
But the senior McCain has spoken quite directly about the war itself: The United States can, and must, win it, says the senior senator from Arizona, held as a POW in Vietnam.

Democratic presidential nominee Barack Obama promises to bring most troops home from Iraq within 16 months of election as president. He has no personal connection to the deployments in this conflict. He is a father of two young girls.
Among all these families, it would seem, there should be an urgency about settling the American score in Iraq.
And, even though Sept. 11 has nothing to do with it, this somehow seems an appropriate day to be talking about all this. As President Bush repeatedly insists, the U.S. is fighting terrorists in Iraq so it doesn't have to fight them at home.-- and three of the four families who hope to succeed Bush and Cheney in Washington are fighting the war in Iraq, in their own ways.
.
Bush says the troops will be "return on success'' - and he has made what is probably his last withdrawal of forces from the war in Iraq before his own retirement, with the announcement this week that 1,000 Marines will leave Iraq in November.
In an election year in which the long-running war has taken something of a backseat to economic turmoil at home, almost everyone involved in the pursuit of the White House has a personal connection to a conflict which most Americans, as the polls clearly show, now consider a mistake.
