SANFORD’S SILLY SOJOURN…. I think I’ve got it — South Carolina Gov. Mark Sanford (R) secretly traveled to Argentina last week because he thought it might count as foreign policy experience.

I hope he’s not too disappointed when it doesn’t.

As you’ve probably heard, the governor has called a press conference to discuss his bizarre behavior, which will get started around 2 p.m. (eastern). I’m going to go out on a limb here and guess there will be more than a few reporters on hand for the Q&A.

There’s no shortage of possible questions for Sanford to answer, but some of the inquiries that come to mind…

* Where did Sanford stay during his trip? And with whom? (The governor refused to discuss his accommodations in Argentina earlier today.)

* Did Sanford lie to his staff, or did he encourage his staff to lie to us?

* Why didn’t the governor tell his wife and children where he was going?

* Why didn’t Sanford check in with the U.S. embassy in Buenos Aires?

* The governor’s vehicle parked at a South Carolina airport had a “baseball cap, running shoes, sunscreen, a pair of shorts, a canvas bag and a sleeping bag” inside. Did Sanford intend to come home and pretend that he actually was on the Appalachian Trail during his absence?

* Why did Sanford change his travel arrangements for his return trip home?

* Who was in charge of the South Carolina executive branch for the last six days?

* Given the number of telephones and computers in Buenos Aires, why didn’t Sanford call and/or email anyone on his staff or in his family?

Sometimes, there’s a reasonable explanation for a seemingly unreasonable situation. I can’t wait to hear what Sanford has come up with.
