I don't use party labels to refer to philosophies.
The Democrat party harbors everyone from neo-liberals to social democrats (very few of these)
The Republican Party harbors everyone from fascists (very few of these) to neo-liberals.
Thus, the party names themselves have little meaning. I consider Reagan, Clinton (Bill), Obama, and Clinton (Hillary) neo-liberals. Bush I was a more classical conservative, while Bush II is somewhere along the lines of Juan Peron. It's not just that this wife's more popular than he is; his administration is also rather fascistic.
Edwards is, at this point, the only Social Democrat in the race, which explains my earlier endorsement.
