I'm not sure more candidates need to announce there. But as a former resident of Philly, I wish the founding documents were kept there rather than being buried in apocalyptical vaults in DC.
Shouldn't the Bill of Rights, including the 27th Amendment be kept in New York City?
And any new amendments should probably be kept in the new capital.
What about the still-pending amendments?
And any proposed amendments. If they were displayed in Philadelphia or Washington there might be simple tote board of ratifications. Surely it would be better to have a gigantic display on the side of the Constitution Casino in Las Vegas?
If a state legislature were considering ratification, it could be displayed on a map as sort of like a pulsating heart. And there could be a sort of bar chart reaching up to the 38th floor keeping track of the ratification, with LED lights screaming up to the current level. Giant holographic images of the founding fathers, imagine George Washington doing Viva Las Vegas.
