It's interesting that you see it that way. From my perspective, it's something that was originally designed with fairly good intentions, that is now being abused by the minority to impose their will upon everyone.
Let's not forget that Democrats have won the popular vote in all but one presidential election this century. And that the Senate's structure has allowed the party representing a minority of Americans to reshape the federal judiciary for years to come. (And unless a rabbit gets pulled out of a hat somewhere, they'll still have outsized control over judicial confirmations for at least the next 2 years.)
I'm all for preventing the tyranny of the majority, but these features of US government haven't resulted in moderation, they've resulted in tyranny of the minority.
