Who said the filibuster technique is useless now that we have a "nuclear option" and a "Slaughter rule"?
The art of filibuster is alive. But instead of the Senate using it, the President has taken over. If you have the stomach for it, you may want to watch this interview and see if you can count the times that a question is asked, but never answered.
The Presidents supporters will probably say; "Oh, it's just politics, they all do it." Which, although true, is not OK. So much for the most open and non-partisan administration ever.
(Extra credit if you can actually watch the whole thing.)
