We should go back to indirect election of senators. Something needs to represent the will of the states as distinct entities.

Having some slimy Mitt Romney types doing math about various state industries and interests when wording bills and trading votes would be a huge improvement over the equally slimy jerks we have now scheming up ways to serve their donors (who's interests correlate with the voters even less than the state's despite that bar being low to begin with) while leveraging abortion this guns that wedge issues to get re-elected despite screwing their voters.

The distribution of senators to states would also matter less if they weren't direct elected and therefore as beholden to party platforms and funding systems and whatnot.
