No person has done more in living memory to undermine the functioning of the US government than the Senate majority leader, Mitch McConnell.
Yes, Donald Trump has debased and defiled the presidency. He has launched blistering attacks on Democrats, on judges he disagrees with, journalists who criticize him and the intelligence community.
But McConnell is actively and willfully destroying the Senate.
Last Wednesday he used his Republican majority to cut the time for debating Trump's court appointees from 30 hours to two, thereby enabling Republicans to ram through even more Trump judges.
McConnell doesn't give a fig about the Senate, or about democracy. He cares only about winning. On the eve of the 2010 midterm elections he famously declared that his top priority was for Barack Obama "to be a one-term president."
Between 2009 and 2013, McConnell's Senate Republicans blocked 79 Obama nominees. In the entire history of the United States until that point, only 68 presidential nominees had been blocked.
In response, McConnell fumed that "breaking the rules to change the rules is un-American." If so, McConnell is about as un-American as they come. Once back in control of the Senate he buried Obama's nomination of Merrick Garland for the supreme court by refusing even to hold hearings.
Then, in 2017, McConnell and his Republicans changed the rules again, ending the use of the filibuster even for supreme court nominees and clearing the way for Senate confirmation of Trump's Neil Gorsuch.
Step by step, McConnell has sacrificed the Senate as an institution to partisan political victories.
There is a vast difference between winning at politics by playing according to the norms of our democracy, and winning by subverting those norms.
To Abraham Lincoln, democracy was a covenant linking past and future. Political institutions, in his view, were "the legacy bequeathed to us."
On the eve of the Senate's final vote on repealing the Affordable Care Act in July 2017, the late John McCain returned to Washington from his home in Arizona, where he was being treated for brain cancer, to cast the deciding vote against repeal.
Knowing he would be criticized by other Republicans, McCain noted that over his career he had known senators who seriously disagreed with each other but nonetheless knew "they had an obligation to work collaboratively to ensure the Senate discharged its constitutional responsibilities effectively."
In words that have even greater relevance today, McCain added that "it is our responsibility to preserve that, even when it requires us to do something less satisfying than 'winning.'"
Political success should never be measured solely by partisan victories. It must also be judged by the institutional legacy passed onward. The purpose of political leadership is not merely to win. It is to serve.
In any social or political system it's always possible to extract benefits by being among the first to break widely accepted norms. In a small town where people don't lock their doors or windows, the first thief can effortlessly get into anyone's house. But once broken, the system is never the same. Everyone has to buy locks. Trust deteriorates.
Those, like Mitch McConnell, who break institutional norms for selfish or partisan gains are bequeathing future generations a weakened democracy.
