I suspected I would get virulently partisan and historically dubious responses, and you did not disappoint, my friend. Thanks for that.

1) Harding gets a pass because he only appointed the crooks to his cabinet. That's unique. I suppose it's because he didn't personally profit, like Trump does.

2) Your ignorance of Coolidge and his policies does not surprise me. March 1929 (left office)-October 1929 (stock market crash) does not 2 years make, even using "conservative" math. Even Coolidge admitted he bore partial responsibility for the crash.
Quote
Although Coolidge had received a great deal of credit for the prosperity of the 1920s, he recognized that he bore some responsibility for the severe economic downturn. He admitted to friends that he had spent his presidency “avoiding the big problems,” as William Allen White quoted him as saying in his biography, “A Puritan in Babylon.” Coolidge died of a heart attack at the age of 60 at his Northampton home on January 5, 1933.
History Had he not died during the depth of the Depression, he might have taken more blame. But, it was his laissez faire policies from 1923-1929, love of tariffs, and cheerleading for reckless stock speculation that created the conditions that led to the failures. Hoover actually saw it coming and tried to warn him. (It seems funny/typical to excuse Republican presidents who serve multiple terms from responsibility for their policies, but blame Democrats for conditions before they even assume office...)

3) I actually give Hoover credit for trying to do something, if way too late. But all three, Harding, Coolidge and Hoover, had a marked disdain for the downtrodden and an overweening belief in the goodness of business.

4) Then, deflect, defame, obfuscate and misrepresent (why am I not surprised?) to avoid the reality of FDR's success, despite Republican intransigence and interference. (And you have the temerity to make accusations about claims of racism you know I never made. Dishonest, much?)

5) Eisenhower (not Nixon) created both the Vietnam crisis and the Bay of Pigs plan (in March 1960 he allocated $13.1 million to the CIA to plan Castro's overthrow. The CIA proceeded to organize the operation with the aid of various Cuban counter-revolutionary forces, training Brigade 2506 in Guatemala. Eisenhower's successor), or did you forget that part of history for convenience sake? It's true that John F. Kennedy approved the final invasion plan on 4 April 1961, only 2 1/2 months after taking office. He was snowed by the CIA about its likelihood of success, and was badly hurt by its failure.

"And the rest," as they say, "is fantasy..." You do make it hard to catalog all your mischaracterizations, but it keeps me occupied.
