If Texas Gov. Rick Perry declares a run for the Republican presidential nomination, it likely would be one of the few times since 1860 that the idea of secession would be a prominent topic in a White House campaign.

Journalist Scott Carney figures he's worth about $250,000, but that number isn't based on his savings or his assets; it's what Carney thinks his body would fetch if it were broken down into individual parts and sold on what he calls the "red market."
