Sure seems like the same thing to me. Both are preventing bills that have enough support to pass from coming up for a vote, which not only prevents them from becoming law but also keeps lawmakers from having to go on record opposing them. There is self-interest in both, and party interest in both, and the country's interest in neither.
Dude, are you unable to read what you post?
According to the Supreme Court ruling in United States v. Ballin (1892), changes to Senate rules could be achieved by a simple majority. Nevertheless, under current Senate rules, a rule change itself could be filibustered, with the votes of two-thirds of those senators present and voting (as opposed to the normal three-fifths of those sworn) needed to end debate.[1] Despite this written requirement, the possibility exists that the Senate's presiding officer could on motion declare a Senate rule unconstitutional, which decision can be upheld by a simple majority vote of the Senate.
Doesn't matter if a simple majority could vote to change a rule, it required a super-majority to even take the vote. If you can't end debate and have the vote, then your fifty-one Senators can change absolutely nothing. That is the entire point of the filibuster, giving the minority party* some power. What Reid did - and I agree with him on this - was declare the filibuster on nominees to be un-Constitutional. Unfortunately, to do this over the Pubbies he had to abolish the cloture requirement on rules changes, and THAT is the real sea change here.
Note that this was not only the minority political party. The filibuster is useful for protecting all kinds of minority interests, such as lightly populated states preventing heavily populated states from using them as waste dumps or voting themselves all the lucrative government projects, or heavily populated states preventing medium and lightly populated states from establishing crowding taxes, or coal-using states stopping oil-using states from banning coal. Unfortunately when we went to direct election of Senators we pretty much reduced the Senate to party politics. Today the filibuster is one of the few tools available for keeping our biennial beauty pageant from swinging our nation from one extreme to the other and we can't wait to get rid of it.
