ABC News reports on a Republican party celebrating the life of Johnny Cash, but understands that there is a question in many people's minds about which party Cash would have stood for. His son says he would never have said and Roseanne Carter Cash says the estate supports the party because it is led by a friend of her father's but not because it supports the Republican agenda.

However, I think the article says it best with this quote,
"With a rough voice, Cash sang about the poor and the imprisoned. He said his black clothing symbolized the world's downtrodden people."

since when do Republicans care about the poor and the imprisoned? the world's downtrodden people? I would suggest Cash was not proud of either party and would hope that anybody who likes his songs would be more aware and more willing to help those Cash sang about.
