Ah, don't you just love historical revisionism?
Reagan turned around the malaise economy of the Carter years and led the US to a stronger economy through the 80s; there was only a minor downturn in the Bush Sr. years due to his going back on his "read my lips: no new taxes" pledge, and if he hadn't done that, he might have won reelection. Clinton rode high on NAFTA and the dotcom bubble, and about the best that can be said was that he didn't do much regulatory strangulation to my knowledge.
The recession in 2008 was (if memory serves) spearheaded by the Democrats who made it possible to do all the stupid shit that caused it in the first place, and Obama didn't do shit to "save" the economy. The assholes who caused it got off scot-free with golden parachutes, the Fed printed an assload more money to bail out the companies that were "too big to fail," and the whole problem got kicked down the road without being resolved. Meanwhile, Obama threw one regulation after another at the economy, leading to one of the most sluggish recoveries in our history (remember how we were all supposed to accept <2% GDP growth as "the new normal?").
Trump took the boot off the economy's neck and cut back on loads of red tape, and business responded in kind by expanding rapidly. Things went pretty smoothly until the coof happened and blue states sabotaged their own economies to stick it to the Bad Orange Man. Frankly, if this is Biden "fixing" Trump's economy, I'd hate to see what he'd do if he actively wanted to destroy it.
