Here’s the next political truism that Trump might overturn

The 2020 election may test as never before one of the most enduring rules of presidential politics, the straightforward four-word maxim coined by Democratic strategist James Carville in 1992: “It’s the economy, stupid.”

Even amid record-low unemployment, robust economic growth and a roaring stock market, President Donald Trump has shown no signs of expanding his support beyond the roughly 46% of the vote that he carried in 2016.

National surveys now routinely find a huge falloff between the share of Americans satisfied with the economy and the percentage that approve of Trump’s performance as President. And new academic research has concluded that attitudes about the economy were much less powerful in driving voters’ decisions in 2016 and 2018 than their views about fundamental cultural and social changes, particularly race relations and shifting gender roles.
