It has everything to do with th number of voters. One massive change would be that the US Senate would not see fit to stick its nose into the affairs of the separate and sovereign states as they would not be pandering for votes from the illiterate and ignorant who base their entire decision on what government should do purely on emotion.
They would instead return to the business of this nation of states as a whole. Would there still be issues of theft or grifting? Of course, but just because Senators would still see some kickbacks that doesn't mean they should also see the immediate gratification of getting calls from sheep voters promising to send them to Congress again.
As the Senate is currently filled with 101 political hacks, an immediate plus is that our airwaves, radio and television, wouldn't be filled every four to six years (depending on the cycle in your state) with empty promises from mediocre politicians who couldn't survive in private industry
The next step to return to a Constitutional Republic would be to drop popular election of the President
DiLorenzo bump
The state legislatures currently abound with the "illiterate and ignorant". Take the Virginia legislature for an example ~ Gag gag gag gag gag gag gag!!!! gag gag gag
