Has anyone read the Seventeenth Amendment?
In regards to bore's line of questions: yes, the Seventeenth Amendment currently allows for any amendment that has passed the Senate once to be brought up for a vote as many times as needed by a regional body once it has passed the Senate. Each regional body can choose to set the method of ratification of an amendment as a public vote of citizens of the region, or as a majority of the region's legislature. Yankee also more or less answered how I'd deal with the public vote: I would like the DoFE to administer the voting booth on the first vote of any amendment for all of the regions, and subsequent attempts would be handled by the regions.
Repealing the Seventeenth as-is would also present a huge, new problem that we haven't had to consider for over a year:
if an amendment fails to pass in four regions on the first go, then the entire process would have to head back to the Senate in order to be voted on again. That's ridiculous. I also have wondered from time to time what percentage of the game actually is aware that when a proposed amendment fails to garner support in four out of five regions on the first vote, that it can be voted on again and again by that region.
Even if a clause were added to ensure that amendments don't have to work their way back through the Senate each time they are proposed to the voters, I also like the idea of each region being able to change the method of ratification. It adds a bit of spice to the game and allows for more fun - again, assuming people are actually aware of it.
