Article 5... I believe the states can call for a Constitutional Amendment, bypassing the Congress. I agree with your premise and add that the Judiciary should be fixed as well. Elemiate all case law and start from scratch. Punish Judicial Activist that clearly misinterpret the Constitution. Fire or fine those who have sworn to uphold the Constitution and clearly violate their oath. I believe it requires 3/4 of the states to accomplish this. This would be "The Seconding Founding" which is long over due.
