The sheep disguised one can be changed, yes. It gets it's power by being more appealing than the other guy. That power can be used to change leadership into a more representative one.

But until it is, it's still an antagonist. To be clear, I don't think democrats and republicans are the same. But democrats marching towards the "center" isn't just bad strategy, it's leadership's preferred shift for the Overton window. It's why they always fight against the left tooth-and-nail, but easily slide to the right to capture the "no one that will vote for them" over there.
