A timely warning to the US, too - as more and more Senate votes are being decided by 50% majority rather than their traditional 2/3 (EDIT: sorry, 3/5). That both parties indulge in it should be worrying to everyone.
It still is. Filibusters have been banned only for confirmations of appointments by the President.
I don't agree. The U.S. Senate is very powerful; those restrictions aren't very broad.
> the simple 50% majority is by design
It depends what you mean. The filibuster, which requires 60% majority, has been part of the Senate since around the 1840s; clearly many generations of Senators thought it was important and intended that it continue.
It is ... it's still there, just not for confirmations of appointments by the executive branch.
