Bill Clinton supported and signed NAFTA, and deregulated the banks literally insuring the 2008 financial meltdown, and in turn leading to the ever growing collapse of the dollar.
as big of a total scum of an individual and leader as Trump is, Bill left a high bar as a terrible prez.
that said, covid made for a bad leader to be a total disaster, which perhaps works in Bill's favor in not being the worst of the terrible.
that said, GW Bush lied his ass off to take us into a permanent state of war, (for which he should still be in prison), and destabilized the middle east. (and did little to nothing positive to offset the horrible he did).
and Reagan killed the working and middle class for the last 40 yrs and still counting, just so the rich could get much richer.
Obama on the other hand, was merely a massive disappointment who totally frittered away his chance.
that said, as beyond bad as Trump has been, he still has a long way to go to be anywhere near as bad as Reagan, Clinton, or GW.
i guess the reason Obama is thought of as well as he is, or papa Bush, is due to their being compared against total and complete sht since 1980.
