its pretty objective if you measure it in terms of infrastructure.

- rate of new miles of roads - rate of increase/decrease in potholes per 10 miles - number of bridges that need fixing - number of people on government assistance - percentage of population in jail - peoples test scores on standardized international tests

its not like things are unmeasureable... just that politics awards those who ignore these things

Not objective at all. There are a lot of values and politics embedded in the things you chose and the implicit direction that is healthy for infrastructure. And it should be, because “objective” metrics are inevitable gamed and their value is gone.
