I think as the Democratic Party discusses the future of governance, it needs to address two major problems: the filibuster, and malapportionment of the Senate.
Both are serious problems and both, I think, actually could be solved by a single, simple rule change.
The filibuster, the rule that any senator can shut down debate of a bill and 60 votes are needed to end debate, used to only be used in exceptional cases, but now it's used on every bill for partisan reasons.
Change the filibuster so that instead of cloture requiring 60 votes, it requires any group of senators representing a majority of the U.S. population.
First, it lowers the threshold to end debate, meaning it's harder for individual partisans to blockade the Senate.
Second, it ensures that no bill can be advanced without representation for the majority of the population approving of it.
Because if not this idea, then we have to do SOMETHING. /end
