Take abortion for instance. I think if a Democrat came around and said “no abortion is a good abortion” and created a policy to reduce abortions not through prohibition but through funding research of new contraceptions, family planning, and education, that could make for a widely popular platform.
Or for immigration, how about we let States determine how many migrants are allowed to live and work there? If California wants to welcome lots of immigrants, let them. If Wisconsin doesn’t want any, that’s fine too. Let’s have a visa program that limits which states they’re allow to live an work in.
Regarding health care: single payer is not going to happen. But why is the debate cast as there only being two options—single payer and the system we have now? Single payer is very rare throughout the world, and the best health care systems are not single payer. Perhaps we could have something like Medicaid for all, ie provide very basic coverage to everyone, and then most people will have private insurance on top of that? There are a whole bunch of other options that no one is even talking about.
I could go on. There are pathways to cooling the animosity between the two parties. Of course, Fox News and CNN and Twitter and Facebook make their money by riling everyone up and pitting us against each other.
