Why don’t we keep going with ballot referendums? It seems like the best proof of concept for change in the modern American political quagmire. How do you get marijuana legalized? You sure as hell aren’t going to find the political spine in the house/senate/executive to pull it off at the federal level. The state level also seems to have a scaled down version of the federal quagmire if you rely on the state legislatures to dictate the initiative. But that ballot referendum just seems to work. People vote, it passes, a state gets what it wants. Then, other states follow suit, and voila, you just scaled something as once-obtuse as marijuana legalization from one state to fifty, effectively replicating federal law. Now rinse and repeat and get other things passed. It seems like the ultimate short circuit for this circus.
