Let's step back a moment and consider "politics." (I'll intellectually coast on this one and reference Wikipedia.)
It is very often said that politics is about power.
Politics (from Greek: πολιτικός politikos, definition "of, for, or relating to citizens") is the process of making uniform decisions applying to all members of a group. It also involves the use of power by one person to affect the behavior of another person. More narrowly, it refers to achieving and exercising positions of governance — organized control over a human community, particularly a state. Furthermore, politics is the study or practice of the distribution of power and resources within a given community (a usually hierarchically organized population) as well as the interrelationship(s) between communities.
Given that "politics is about power," it should not be surprising that, to use another saying, "power corrupts." We should not be surprised that politics results in the rise to power of individuals who are corrupted by the power they seek and hoard.
Our system of government is not immune to such individuals. Bill Moyers provides examples. Likening it to a virus:
In America, the virus has taken many forms: “Pitchfork Ben” Tillman, the South Carolina governor and senator who led vigilante terror attacks with a gang called the Red Shirts and praised the efficiency of lynch mobs; radio’s charismatic Father Charles Coughlin, the anti-Semitic, pro-Fascist Catholic priest who reached an audience of up to 30 million with his attacks on Franklin Delano Roosevelt and the New Deal; Mississippi’s Theodore Bilbo, a member of the Ku Klux Klan who vilified ethnic minorities and deplored the “mongrelization” of the white race; Louisiana’s corrupt and dictatorial Huey Long, who promised to make “Every Man a King.” And of course, George Wallace, the governor of Alabama and four-time presidential candidate who vowed, “Segregation now, segregation tomorrow, segregation forever.”
Note that many of these men leavened their gospel of hate and their lust for power with populism — giving the people hospitals, schools and highways. Father Coughlin spoke up for organized labor. Both he and Huey Long campaigned for the redistribution of wealth. Tillman even sponsored the first national campaign-finance reform law, the Tillman Act, in 1907, banning corporate contributions to federal candidates.
But their populism was tinged with poison — a pernicious nativism that called for building walls to keep out people and ideas they didn’t like.
Which brings us back to Trump and the hotheaded, ego-swollen provocateur he most resembles: Joseph McCarthy, US senator from Wisconsin — until now perhaps our most destructive demagogue. In the 1950s, this madman terrorized and divided the nation with false or grossly exaggerated tales of treason and subversion — stirring the witches’ brew of anti-Communist hysteria with lies and manufactured accusations that ruined innocent people and their families. “I have here in my hand a list,” he would claim — a list of supposed Reds in the State Department or the military. No one knew whose names were there, nor would he say, but it was enough to shatter lives and careers.
Eventually, McCarthy was brought down by a journalist (Edward R. Murrow at CBS) and a lawyer (Joseph Welch) in the (should be) well-known Army-McCarthy hearings. (See Moyers' post for a summary - if you need it.)
But the interesting thing here is that Donald Trump has intellectual and political roots in McCarthyism. As Moyers put it, if you draw a Venn Diagram of Trump and McCarthy, you will find at the intersection a fellow named Roy Cohn. Moyers explains.
Cohn was chief counsel to McCarthy’s Senate Permanent Subcommittee on Investigations, the same one Welch went up against. Cohn was McCarthy’s henchman, a master of dark deeds and dirty tricks.
Cohn taught Trump how to use "dark deeds and dirty tricks." That is, until Cohn was diagnosed with AIDS and then Trump dropped him like a hot rock. (Politico.com has that story.)
Cohn introduced Trump to his McCarthy-like methods of strong-arm manipulation and to the political sleazemeister Roger Stone, another dirty trickster and unofficial adviser to Trump who just this week suggested that Hillary Clinton aide Huma Abedin was a disloyal American who may be a spy for Saudi Arabia, a “terrorist agent.”
Cohn also introduced Trump to the man who is now his campaign chair, Paul Manafort, the political consultant and lobbyist who without a moral qualm in the world has made a fortune representing dictators — even when their interests flew in the face of human rights or official US policy.
So the ghost of Joseph McCarthy lives on in Donald Trump as he accuses President Obama of treason, slanders women, mocks people with disabilities and impugns every politician or journalist who dares call him out for the liar and bamboozler he is. The ghosts of all the past American demagogues live on in him as well, although none of them have ever been so dangerous — none have come as close to the grand prize of the White House.
Joseph Welch said it best.". “Have you no sense of decency, sir, at long last? Have you left no sense of decency?… If there is a God in heaven, it will do neither you nor your cause any good. I will not discuss it further."
But Republicans have a need to discuss it further.
As this headline in The Huffington Post aptly put it, “Republicans Are Twisting Themselves Into Pretzels To Defend Donald Trump.” Ten GOP senators were interviewed about Trump and his attack on Judge Curiel’s Mexican heritage. Most hemmed and hawed about their presumptive nominee. As Trump “gets to reality on things he’ll change his point of view and be, you know, more responsible.” That was Sen. Orrin Hatch of Utah. Trump’s comments were “racially toxic” but “don’t give me any pause.” That was Tim Scott of South Carolina, the only Republican African-American in the Senate. And Sen. Pat Roberts of Kansas? He said Trump’s words were “unfortunate.” Asked if he was offended, Jennifer Bendery writes, the senator “put his fingers to his lips, gestured that he was buttoning them shut, and shuffled away.”
No profiles in courage there. But why should we expect otherwise? Their acquiescence, their years of kowtowing to extremism in the appeasement of their base, have allowed Trump and his nightmarish sideshow to steal into the tent and take over the circus. Alexander Pope once said that party spirit is at best the madness of the many for the gain of a few. A kind of infection, if you will — a virus that spreads through the body politic, contaminating all. Trump and his ilk would sweep the promise of America into the dustbin of history unless they are exposed now to the disinfectant of sunlight, the cleansing torch of truth. Nothing else can save us from the dark age of unreason that would arrive with the triumph of Donald Trump.
Sense of decency? Not in the Republican party.
Update: Check out Fareed Zakaria's op-ed in the Daily Star this morning. He criticizes those Republicans who remain silent about Trump's lies.
