The idea, I think, is to reach a threshold where these progressive ideas cause a sea change and we start to see a momentum shift. We then will see a slide down the hill of progressivism into a more powerful role in government. We're seeing a lot of resistance but I also think we're in the beginning of this sea change. As the Republicans move further right, it's only natural that Pro-worker, pro-abortion, etc... candidates get more support. The Democratic moderate will be pushed left as they distance themselves from Republican (far right) ideas. We're seeing this in real-time.
