There was, of course, a reason why Congress and the legislative branch is outlined in Article I of the Constitution. While we have three co-equal branches, the legislative branch was to be the first among equals. Within the Congress, moreover, the House of Representatives was supposed to be more prominent than the Senate overall.
Of course, that is not the present situation, as Klein explains:
But that hierarchy has been tossed on its head. For all practical purposes, the House is less powerful than the modern Senate and Congress has taken a back seat to the president. The reasons for the preeminence of the president are complicated, but a big reason that the Senate has stepped to the forefront of modern politics is that it's less democratic than the House, and thus most attention focuses on whether it can pass legislation, and most compromises focus on helping it pass legislation. That's unavoidable given the filibuster's centrality to the system, but it's not a good state of affairs, and it is not how the Founders intended for things to go.
It is just one more reason for why we should work to eliminate the Senate filibuster.
