The music was definately Zydeco and was played in a bar that is in the home town of Zydeco music, The Whirlybird in Opelousas.
I recognise most of the musicians and others in the video, and they are all very fine musicians and real good folks.
As for their politics, being an Englishman, I dont know and I dont really give a damn.
Music has always played a part in political campaigns but this is the first time I heard it done Zydeco.
Wish I'd a been there, dancin' an eatin' boudin an' a good gumbo or jambalaya. Yai-ii shere! I gawantee.
