"Nobody( except for Ron Paul and formerly Trafficant) talks about abolishing the income tax."
I believe Jim Trafficant was motivated to fight with the IRS because they made him pay taxes on money that he got by illegal means. It was not for us.
Whatever his motives( and I believe they were sincere witnesses are NOT a reliable form of evidence especially in political cases) it doesn't change the fact that he was one of the only pols willing to fight the IRS.
