HOUSTON — In the last few weeks, Democratic presidential candidates have focused on fears of a recession, accusing President Trump of recklessness in handling the nation’s economic affairs.

“The warning signs for another recession are flashing,” Elizabeth Warren tweeted recently. The economy is “teetering on a recession,” Joe Biden said a few days later, probably meaning that it is teetering on the edge of a recession. “We’re now about to enter the Trump recession,” said top Bernie Sanders aide Jeff Weaver. Democrats took note of a Washington Post poll saying that Trump’s approval rating has fallen in light of the fact that 6 in 10 Americans fear a recession will arrive in the next year.
