Three quarters of the States. 38 states. That is what a Constitutional Convention would require.

When the US Constitution was written there were 13 states. That would mean 10 of the states would have to call for a Constitutional Convention. The dynamics were different then. Capitalism was more marginally important and citizens were more subsistence.

Vermont is correct, it is sincerely time to look at the corruption within our federal government only committed to politics and determine whether a Constitutional Convention is necessary. I think it is time. Could mean that more, but, with such drastic changes possible the approach has to be careful to say the least.

My first instinct tells me working out through elections, the courts and other methods of citizen resolve would be best, but, considering how dependent our democracy has become on a few wealthy citizens and the threat of our dreams taken away as with housing, it would seem more than logical to approach this option given to us so very long ago.

The truth is the Red States basically out number the Blue States. However, the Red States are dependent on the Blue States. That is leverage. It is leverage enough for the Blue States to make the Red States understand if they rock the boat too much it would disturb their ability to be donor states. So, while the Blue States are out numbered and there is only 38 states needed for a Constitutional Convention, the Blue States have a lot of clout they could bring to the proceedings and process. 

It is possible to cleanse the country of the corruption and address it's problems with minimal risk if it is done well.
