Trump has the worst approval rating of any president in history  

It's a pity. Trump never broke 50% approval, ever. Biden, for half his term, has been above 50%, in fact in the mid 50s

Trump was consistently in the dumpster:

Facts don't lie - In fact, he's the only president in 30 ish years to lose as an incumbant. Being in the low 40s for his entire presdidency didn't help.
