You have the kernel. I hope you develop it in a stand alone vanity.
After repeal of the 17A, a virtual senate that features senators with offices adjacent to state legislative chambers is worth considering.
Still, legislatures are personal in nature, so I’m not sold on a entirely virtual congress, but certainly look forward to your ideas.
A virtual Senate with senators' offices in the state legislatures would make sense. The repeal of the 17th Amendment could also end the six-year term of senators and make them "at will" employees of their respective legislatures. If there is a party change in the state legislature, the new legislature would be able to change their senators as befits a change of state policy toward the federal entity.
A total virtual Congress would solve a lot of problems of a very large country.
