More than a few Republicans and even some Democrats think that Trump spurred or led the Republican Party to the “dark side.”
Unfortunately, that explanation ignores the fact that there’s been a dark side to the Republican Party for at least seventy years, beginning with Joseph McCarthy in 1950, and his mythical and essentially non-existent list of 205 Communist Party members working at the State Department. Republicans were so fearful of losing McCarthy’s support in the 1952 election that they insisted that General Dwight Eisenhower remove a paragraph in a speech in Wisconsin that attacked McCarthy as a dangerous demagogue and fabricator. Although Eisenhower later said he regretted that decision, he never did confront McCarthy directly.
Richard Nixon used abusive and misleading anti-Communist themes in getting elected to Congress and the Senate (where he claimed that a “pink sheet” proved that his liberal opponent was an avowed Communist, which she never was).
Then in 1961, Senator Barry Goldwater pushed William Buckley and the conservative National Review to go easy on Robert Welch and the John Birch Society, even after Welch had claimed that Eisenhower was “a dedicated, conscious agent of the Communist conspiracy,” because the John Birch Society had become a well-funded source of volunteers and donors for the Republican Party. The Birchers [who declared that fluoridation was a Communist plot] enthusiastically supported Goldwater and his infamous statement that “extremism in the defense of liberty is no vice.”
In turn, in 1968, Nixon courted Strom Thurmond, the arch-segregationist senator from South Carolina and said he opposed forcing integration and opposed busing and had his campaign manager tell southern Republican party leaders that he’d pick a vice president acceptable to the south and would “lay off pro-Negro crap.”
Despite efforts to whitewash matters, Republicans tend to forget that in July of 1980, Reagan’s first campaign stop was in the heart of Ku Klux Klan territory, Philadelphia, Mississippi, where he declared “I believe in states’ rights,” which was and is the mantra of southern segregationists and white supremacists. The religious right lined up behind Reagan, particularly the preacher Jerry Falwell, who waged a crusade against homosexuals because he claimed they threatened the very existence of the United States. When then-President Jimmy Carter tried to point out Reagan’s ties to the religious extreme right, he was attacked for being mean.
Throughout the 1990s, Pat Robertson claimed that all sorts of Satanic dupes – otherwise known as J.P. Morgan, the Rockefellers, the Federal Reserve, the United States, Henry Kissinger, the liberal elites – were out to destroy the United States, and threw his weight and that of the Christian Coalition behind Newt Gingrich to help the GOP get control of the U.S. House, and six years later backed George W. Bush over John McCain in 2000 (possibly because McCain had far more scruples than George W.).
Then in 2009 came the Tea Party, filled with paranoia, racism, and rage, waving Confederate flags at rallies and claiming that Barrack Obama was a Muslim born in Kenya, that Obama’s health care plan would set up death panels, and that Obama was a full-fledged Marxist who hated white people and was setting up concentration camps for his political opponents. When the Tea Partiers rallied at the Capitol in 2009, the Tea Partiers carried posters showing Obama as Sambo and calling Obama and his supporters “Nazis.” Those same Tea Partiers were welcomed by House Republican leader John Boehner, and Representatives Eric Cantor [later House Majority Leader] and Mike Pence.
Donald Trump didn’t create the hatred and viciousness out of nothing. He merely called it up out of the Republican Party, thrived on it, and encouraged it in every way possible… and only a handful of elected Republicans protested.
