Nitpick on the nitpick: while a cardinal does not rule over other bishops, there are metropolitan archbishops and suffragan bishops. A metropolitan is the head of an ecclesiastical province and doesn't rule over other bishops as such, but is more like a general overseer and symbolic head of the province.
