Provided that the legislators aren't so bound to party doctrine or so corrupt, as some on here have implied, that they would cheerfully sell away their state's sovereignty in order to have their Senators continue to push that party's national agenda (Marxism for Democrats, Socialism for Republicans).
For the repeal to really work, the state legisL00Tures will have to be cleaned up as well. My initial suggestion would be to overturn Reynolds v. Sims, so that one house of each state legislature can be county-by-county again, if it so chooses, thus keeping big-city and suburban RAT politicians from dominating both houses of the legislature, the way they appear to do in Maryland. Another would be to put redistricting duties in the hands of an impartial body, in order to make districts more competitive in elections.
Of course, the wailing and gnashing of teeth from liberals, progressives, and populists will be music to my ears. :-)
Actually, you’d have to overturn Baker v. Carr.
After reading fieldmarshaldj’s take on legislative history, I suspect that corruption has been a problem in local governments all along. In the disant future, scrutiny of local politicians will also be more local. By that time, scrutiny of our Federal leaders will have reached critical mass, and the idea of weakening an informed voter would be even more absurd.
