In 2020, Liberals/Democrats/progressives are the smarter half of the bipartisan system, but back in 1994, a majority of American voters (70-75%) voted for conservatives/Republicans/traditionalists preaching a moral Christian capitalist version of America to dominate congress, but we realize in a pandemic the one side with a more logical humanitarian scientific mindset can help the population defeat covid-19.
Edit: I realized 2020, 1994, 1968 (a very socially liberal period) and 1942 (strong emphasis on patriotism) are every 26 years, about a quarter of a century each. Is there an astrological factor to swing the sociopolitical-cultural pendulum back and forth (and from left to right to back to left) in a cyclical pattern? 1942 had WW2, 1968 had Vietnam, 1994 is post-cold war and 2020 is post-war on terror.
The 1940s was under a New Deal "socialism", 1960s the Republicans was still the "party of Lincoln" in the North, eastern corridor and west coast, 1990s cultural trends of "PC-ness" and 2010s the poor-middle class struggled under the first world's worst social welfare net. Those eras are a hybrid mixture of the Left and Right, somehow the majority of Americans move towards one side over another and is seeking change to improve their lives.
And economic conditions change over time, obviously: 1942 was the 12th? year of the Great Depression, 1968 was the 20th? year of a mid century economic boom, 1994 was the worst recession since the 1970s after a similar economic boom in the 1980s, and 2020 had the 1990s-2010s cycles of boom and bust (the Dot.com bubble burst of 2000-02 and the Great Recession of 2008-10).
