Is "Joe the Plumber" Endorsing Icet For Free? Or For a Fee?

Eli Yokley at The Fuse Joplin asks an interesting question this morning: Is Samuel Wurzelbacher endorsing Allen Icet out of the goodness of his heart?  Or as part of a squeeze-every-dollar-out-my-Joe-the-Plumber-infamy business strategy? 

Either way, Team Tom Schweich is happy to get a dig in. "All of Schweich's events in the past and for future will be all profit for the campaign–meaning no fees for [Mitt] Romney, [John] Bolton, etc," an anonymous Schweich supporter tells Yokely.
