I think he's asking actual libertarians.
Clinton was much more a libertarian than Reagan ever was.
But of the post-Civil war presidents only Cleveland, and possibly Harding and Coolidge (and then not on foreign policy) would count as libertarians.
Didn't Cleveland's economic policies cause some kinda "Great Depression"?
Depends on which economist you talk to. But "The Great Panic" began in 1893, only at the start of Cleveland's Second term which pretty much ended the non-stop growth of the post-civil war period.. where the Republicans had been in power for all but Cleveland's first term (and Andrew Johnston, if he counts). To blame, GC alone for it would be ridiculous. That isn't of course to say his policies weren't a factor, in the same way Coolidge's policies might have been responsible on some level for the great depression.
BTW... it was acctually called "The Great Depression" until the one we now call "The Great Depression" occured.
And I do blame Coolidge's policies for the Great Depression, even though they weren't the primary cause. Had a real economist been President at the time, or had Coolidge bothered to consult one, instead of the millionaires he surrounded himself with, then he could have seen that there were bad signs coming up from the bottom that signaled economic troubel ahead and he coudl have done something to head it off. Instead, we got Hoover's "too-little, too-late" policies and Hoover is blamed for the Depression, even though he didn't do a damn thing to cause it.
Coolidge was obviously a genious, though. "The business of American is business." How insightful? [/sarcasm]
Many economists actually attribute the Great Depression to the Federal Reserve. Yet, amazingly enough, The Great Depression didn't happen during the laissez-faire Harding and Coolidge administrations and didn't happen until the anti-capitalist Hoover took office.
