TUA President Jim Tobin was on The Tom Woods Show talking about his past and present as a tax fighter. 

Very nice chat today with Jim Tobin, founder of Taxpayers United of America, who was chronicled by an admiring Murray Rothbard in 1977. He’d just finished reading volume three of Rothbard’s Conceived in Liberty (a four-volume set now available in a single volume), on the colonial period and the American Revolution, and felt inspired.
I suspected the D.C.-connected Tea Party groups would have shunned him, since he actually wants to cut taxes and has even led tax strikes. I was correct, as Tobin explains in our discussion. Have a listen!
