well, corruption aside, I’d rather that the Public vate for Senators, thus they have to answer to and convince their constituents to cast their their vote between the candidates, than only need convince and influence a few hundred people. After all, it’s not unusual for Legislatures to thumb their noses at the people and do what’s in their own self-interest.
Not uncommon? I'd say it's the rule. And that's why I prefer the two legislative levels to be in competition with each other. As it stands now the states are just administrative subdivisions of the whole. Previously the states could use the power to choose senators as a check on the power of congress - that's why the senate was created. With the senate being democratic why even have it?
