The week after the election, I posted this on Threads:

Someone born in one year, 1946, has led this country for 20 of the last 32 years—and if Tubby lasts his term it'll be 24 of 36. All from one year. All from a few summer months. All from some postwar fucking in the fall of '45. And we've been fucked ever since. 

In the post, I mention '50s babies because my wife is one, but '30s babies (my father) haven't exactly been represented, either. If you expand it to incude every U.S. president born in the 20th century, you get this by decade:

• 1900s (1): LBJ (1908)
• 1910s (4):  Reagan (1911), Nixon (1913), Ford (1913), JFK (1917)
• 1920s (2): Carter (1924), H.W. Bush (1924)
• 1930s (0)
• 1940s (4): Biden (1942), Clinton (1946), W. Bush (1946), Trump (1946)
• 1950s (0)
• 1960s (1): Obama (1961)

JFK was famously the first 20th century president, “born in this century” as he stated in his inaugural address in January 1961, which is pretty crazy. We're 61 years into the 20th century before getting a 20th century baby? Even crazier: four of the next five presidents were older than him. We went young in '61 and then ... “Nah.” That's our story. Great leap forward, retreat. Progress, regress. Change we can believe in, make American great again.

The regress has gone from Nixon to Reagan to W. to Trump. The arc of American history is short but it bends toward stupidity.
