>> what does it mean to be a liberal redneck? >> you just embrace the good parts about being from the south, which is just having a good time, you know, raising hell, football, all that stuff. but you're not a hateful, awful, inbred hick inbred hick person. >> i'm a poor white trash redneck from the admit of nowhere in did that. in tennessee. i am also a well-educated, well-traveled, godless >> reporter: a rebel yell across the partisan divide. >> the south cooks better chicken, plays better football, and sings sweeter songs. to act like we bring nothing to the table culturally is fake liberal hypocritical [ bleep ]. >> reporter: with millions of views he seems to be on to something. >> this election day, 40%-odd of the people in mississippi will vote for frirk, 40%-odd of the people in california will vote for donald trump. please stop acting like we're in
