How Democratic is your name?

[Cassius]

Ian - 55.9 percent Democratic
Francis (middle name) - 51.6 percent Democratic
Geoffrey (second middle name) - 50.2 percent Republican

Bizarrely, apparently there are nearly 10,000 people called 'Dung', and 16 are called 'Bubbles' (in my view, a cat's name).
