My theory is that if the 17th Amendment were repealed, states with 67% majority control of the state legislature or more would likely appoint two senators from the majority party, and states with less than 67% majority control would have insufficient leverage and be forced to moderate, nominating one member from each party. It won't matter what party the appointees are... the fact that they are appointed by the state legislature and can be recalled by the state legislature means they will answer to the state legislature.
And all the self serving power grabbing trips in the US Senate will stop and the balance between the states and the federal government will be restored.

That's fairy-tale land stuff, pal.
