A legislature of thousands is insane and unworkable. There is no way bring back the fantasy of the “citizen statesmen”, vastly expanding Congress certainly wouldn’t do it. Too many of our citizens are idiots who shouldn’t be allowed to vote.
Having them “telecommunicate” would require a constitutional amendment that will never pass.
I could brook a slight increase of the House though.
The unworkable part is what is alluring to so many. If Congress is stuck in perennial mire, they can’t screw us over by enacting more horrid legislation. But as I stated, that would then legitimize the President ruling via fiat (pen & phone/executive order) to bypass and enact their own agenda unilaterally.
If folks want to see what a mega-Congress would look like, take a gander at the Senate in Star Wars. Of course, they voted to break perpetual deadlock by “electing” an Emperor.
