Anything that would make the USA more democratic and fix all the problems with elections.
The system isn't working and needs to be fixed.
Of course, another problem is war. Any amendment which would make it harder to go to war would meet with my approval.
edit: btw Supreme Court justices should have limited terms. Lifetime appointments don't seem prudent. (although I don't think we need a constitutional amendment for that, that was just a tangent I wanted to consider)
I totally agree with all of that. Fixing the electoral system is one of the most important things we need to do--the current system just ensures the Duopoly of Crap will survive as our sole rulers unchallenged. And something that makes war ridiculously hard would also be great.
