What do you call someone who is republican and democrat?

Since the US is well-known as a country who is divided into 2 political parties, namely the Democrats and the Republican, there are people who identified themselves as neither Democrats nor Republican. They call themselves, Independent. Independents, avoid these labels and would like to vote for whatever party who believes in the same principles as they do.
