We can thank the 17th Amendment for runaway courts.
Thanks to the ill-conceived 17th Amendment, corrupt, state sovereignty-ignoring senators not only help the House pass unconstitutional bills which steal state powers and state revenues uniquely associated with those powers, but also consider the following.
Senators then confirm state sovereignty-ignoring activist justices to the Supreme Court, such justices then declaring the unconstitutional laws which the Senate helped to pass to be constitutional, unconstitutional Obamacare a great example.
The bottom line is that the 17th Amendment arguably effectively repealed the whole Constitution.
