Go back and let State Legislatures select the Senators. By directly voting for Senators we have created six year Representatives like the House. They can't be touched for six years, then their party throws them a bone to help them get re-elected. this is where it became more about party politics than government of the people and by the people. No one is there representing their state in the Senate. they represent their party. there are no recall measures in most cases. Term limits are not necessary. In fact they can be detrimental. Just don't vote for them.
