well, I think Coke outsells Pepsi generally, but I, a sincere Democrat have always preferred Pepsi.....I don't think it is a very profitable idea to judge that way...*grin*

Coke has a 'bite' to its flavor that distinguishes it, and is almost a generic term, like Kleenex, and I suspect that Republicans are more susceptable to "Name Brands", which gives them an edge in this tally.
