The graph you posted shows cloture votes increasing sharply in 1970, certainly way before Geoge HW Bush ever became president. Why don't you actually read that article, the history of the filibuster is quite a long one, as I said.
Dear me you're a fool. You can try and hide that fact all you want, but you clearly said the following which is down and out wrong: "And what, cloture used to be rarely used? Where the hell to you get your info Krezack?"
Moreover, the 'sharp increase' is actually under the Reagan-Bush Sr tenure, it's certainly in full swing for Bush Jr's reign. Regardless of exactly whose term it started in, the point is Cloture never used to be so abused, which you refuse to accept for some reason.
