Being cynical as of late, I can only ,come up with some examples of the bad ones (though I wholeheartedly agree with your asses,net of Coolidge).
FDR might be the worst, IMO, not just for the (disastrous) policies he enacted, but for the sheer arrogance displayed in breaking with tradition and holding the office for four terms. So blinded by the "love" of the people he bought with social programs and economic manipulation, he never saw or cared that he was the worst thing for them.
Wilson, for his complete lack of real-world experience, having been in nothing but academia Iirc. He was susceptible to lofty sounding ideas such as international collectivism and using the power of the gov to quash political dissent....sounds familiar to me!
JFK, for signing an EO allowing federal employees to unionize. We see where that's taken us.
Not sure of the sequence of events off the top of my head, but that may have been why he was labelled as soft on communism, and his last minute withdrawal of support during the bay of pigs invasion certainly gives credence to that claim.
LBJ, from his gawdawful mis-micromanagement (did I just coin a new term?) of the Vietnam war to the rise of the welfare state and destruction of the black family unit. What, something like $37,000,000,000,000 of other people's money and all they got was a solid voting bloc...and generations of pent up racial animosity.
Lincoln, for invading and subjugating a foreign, sovereign nation under false pretenses on behalf of mercantilist s and bankers.
The current asshole is too easy to include. Hell, look at the majority of threads from the last 5 years.
