In June, 2009, South Carolina governor Mark Sanford disappeared from public sight for five days, a period during which neither his wife nor much of his staff apparently knew where he had gone. A Sanford spokesperson eventually told reporters that the Governor was on a secretive hike along the Appalachian Trial to clear his head after a tough legislative session. Turns out that Sanford had actually been in Argentina where he had been conducting an extra-marital affair.
In the case of a Republican, more often than not it'll be a same-sex affair.
I hold a high-stress political job and my wife refuses to give head. I guess I'll have to go hiking the Appalachian when the current legislative session is over.
I'm sorry, Carol, I can't go to your mother-in-law's Tupperware party this evening. I'm hiking the Appalachian Trail with that new secretary from the office... in Argentina.
To travel to Argentina to bang your mistress, while your gubernatorial staff back in South Carolina lies to the press about your whereabouts (see Sanford, Mark).
