A divided Congress will not give 2/3 support for anything at this time. The Congressional opportunity to pass an Amendment to the Constitution is not feasible. The state initiated part of Article V is effectively blocked by the words limited convention and the fear of a runaway convention. An open pre-convention can accomplish the necessary debate and get approval of 34 states for the outline of a Constitutional amendment such as overturning Citizens United. (and or other amendments). After the delegates settle on the basic outline, then the states can follow up with applications to an official Article V convention. The final language of the amendment would be finished at the convention. With the approval of 38 states the amendment will be adopted. It's not easy but other reasonable possibilities have failed. The pre-convention must be called by a state or states. This will give it legitimacy. Ultimately this is completely in line with the outline created by our Founding Fathers.
