Public Policy vs Political Science/Econ Double Major

I have a passion for politics, but I do enjoy economic policy, so I’m considering double majoring in Economics and Political Science. However, I understand that public policy majors are interdisciplinary and include these fields. Would a double major in Econ and political science or a public policy major be more employable in the job market? Which option, if I decide to go, would better prepare me for law school? Thanks in advance.
