Why would the Republicans, as the minority in the Senate, even entertain the thought of limiting one of the few powers they have to keep the American public from being steamrolled with bad, socialist, big government legislation?
Maybe the establishment GOP approve of said bad, socialist, big government legislation, and to the point where they are deliberately removing obstacles to its implementation.
Because they are spineless cowards that do not have any real objections to such big, bad, socialist legislation?
