You must be math challenged. Trump had -31% drop in GDP in the 2nd quarter. There were only TWO quarters left before Biden took office, not THREE.
And for doing the math. Start the economy at a normalized GDP of 100 (for comparison)
2nd quarter it goes down 31%, or down to 69. Then it goes up 33% or up to 92. So Trump is down $3 trillion, and GDP is still down for the year.
Then it goes up 33%
Damn! That's a lot of growth!!!
