One of the big differences between Dems and Reeps is that when the Reeps have power they use it. The Dems spend most of their effort on worrying about what the Reeps will do when they get power again, instead of using the power when they have it.

As you already pointed out, Reeps are for dismantling government for the benefit of the wealthy, while Dems are generally more for equality.

Not that the Dems are 100% pure or infallible, mind you.

You never change things by fighting the existing reality.
To change something, build a new model that makes the old model obsolete.
