Republicans and Democrats don't care about the people in the US. They care about their party over all things. 

If they did, they would support the medicare for all bill. If they cared about the people in the US, the debate over DACA wouldn't be a thing. If they cared about all of the people who make up this country, they wouldn't waste time with this and trying to toe the line so they can keep their funding. If they cared about the US and not keeping their job (which is to represent the people) they would, in fact, represent the people instead of special interest groups.
