Tom Steyer, who announced a few days ago that he is seeking the Democratic presidential nomination, says in this campaign you tube that he favors creating a “national referendum” process so that voters could determine federal laws.
Generally, a referendum refers to forcing a popular vote on a newly-passed law. One wonders if Steyer meant to also advocate for a national initiative process. Congress does so little these days, it isn’t likely that a national referendum, even if it existed, would be much of a vehicle for change.
A federal referendum process, or a federal initiative process, would require a U.S. Constitutional amendment. Thanks to Political Wire for the link.
