Hank Williams Jr.'s Son -- My Dad Should NOT Talk Politics

Hank Williams Jr.'s son -- Hank Williams III -- doesn't think his father should have opened his mouth about Obama yesterday ... telling TMZ most musicians are "not worthy" of a political discussion.

TMZ spoke with HW3 -- and punk rock-meets-country singer -- who tells us, "The only person out there worthy of mixing political views and music is Jello Biafra."

FYI -- Jello Biafra is the original lead singer of the legendary punk rock band Dead Kennedys ... who is now a big shot political figure in the Green Party.

As TMZ previously reported, Hank's dad's famous "Are You Ready for Some Football" jam was yanked from Monday Night Football last night ... after HW2 went on Fox News and proclaimed that President Obama and Joe Biden are "the enemy."

When we asked HW3 about his political views, he told us, "I'm a musician ... not a politician."
