Probably easier than convincing individual senators/reps and the part(ies) as a whole to give up their own personal power with things like Ranked Pairs voting, no?
And probably easier to have Congress pass such legislation to draw a new line in the sand, even if it could be undone later, than doing things that would inescapably require a Constitutional amendment.
The problem with the other reforms I have thought of is that we're so far gone it will take more than one reform. Like campaign finance reform would have been great a decade ago. But now that kind of relies on getting back a non-pwnt and even trustworthy law enforcement apparatus, too. Same with a US GDPR / tech antitrust enforcement - would have been great a decade or two ago, but it won't particularly change much now that half the pop culture is already enamored with fascism.
But I agree that we need to be brainstorming and discussing many approaches to reform. So what specifically are you thinking of as the reforms we need?
