Metrics to evaluate a Presidency

I got lots of helpful comments in my first post, so I’ll try a second: I want to develop a list of criteria by which to evaluate a presidency. Coming up with criteria and metrics on the economy is pretty easy, but I’d like to ask for suggestions on proxies for evaluating:

  • Racial relations;

  • Gender equality;

  • Impact on free trade /​ protectionism;

  • Education;

  • Any other significant factor that would determine whether a president is successful.

Note: a few people have pointed out that the president is restrained by senators and congressmen etc—I realise that; but if we are willing to admit that presidents do have some effect in society, we should be prepared to measure them.
Thanks!
