There are already two Democrat Parties. They just have different names.

Do you mean the CPUSA, the SPUSA, and The Green Party...or did you mean the Democratic Socialists (DSA) and the National Socialists?

(of course that's way more than two)

Now that you mention it, all of them. I sure that if you check close enough or back far enough, you will find some type of ties to the philosophy of the Democrat Party in them.
