The Nation's recent editorial Filibustering The Public makes it quite plain: the filibuster is nothing, if not anti-democratic. It's really as simple as this:
1) Democracy = Majority Rule
2) Filibuster = A Minority 41 Senators Have Final Say = Minority Rule
People think that if a 51% majority rule is good, then a 60% majority, well gee... that sounds even better! Except what this structure actually means is that a 41% minority can stop any democratically supported policy dead in it's tracks.
This is the reason that a handful of special interest (insurance-lobby) senators get to play 'King of the Senate' while ruining an already dilute bill that well over a 50% majority support. It really is despicable, and it's time for real change.
