Then it appears that I crashed this party early. To answer the question, it's pretty tough.
Lincoln was obviously against the States right to secession, even if the people of the separatist states felt they were being harmed by the federal union. However, he did extend The Peoples rights to "negroes". I don't think he's all that bad, because the CSA did a lot to force his hand.
Wilson was against individual rights, via his support for Jim Crow laws, and opposition to womens suffrage. On top of that, he pretty much forced us into the global arena by supporting the First World War. An act that has lead to very anti-Libertarian treaties that we are Constitutionally bound to uphold. He's on the really bad list for Libertarian principals, and I don't believe he has many redeeming qualities as a president, or even a person to be frank.
FDR is a fun one, since he was all about big, BIGGER, and
BIGGEST government. Huge bureaucrat, and the New Deal was a government spending spree,
but he did pull us out of the depression, and he instituted the Indian New Deal, which was a pretty nice move towards human rights, so I can't hate the guy. He had his heart in the right place, and that was with the People. I have to give him credit for that.
I can't say anything bad about TR as a person, nor would I simply because I think he was one of the most bad ass presidents we've ever had, but his policies were not Libertarian in the least. One thing he was for, though: Women's suffrage, a Peoples right. I don't consider him to be bad at all, since his policies weren't really anti-libertarian. He just wasn't Libertarian.
LBJ wasn't too bad, either. He instituted the voters rights act, which prohibited voter discrimination, his civil rights act outlawed segregation, he vehemently went after the KKK and forced them to cut the ****, like murdering blacks, interracial couples, and civil rights activists. I can see a split on that from a Libertarian point of view, but as I see it, he was enforcing the Peoples rights to be free from tyranny imposed upon them in the south. Only big "anti-libertarian" thing I'm aware of is his Medicaid program, and the Gun Control Act of 1968.
I'm not going to address W Bush or Obama, because they're too obvious. Neither has a Libertarian bone in their body, and I don't consider either of them to be the worst.
Nixon, ole tricky Dick, another one of the bad ones. Although "New Federalism" was a good idea, it never happened. He initiated the war on drugs, he also inflicted wage and price controls, inflation still happened, which resulted in all kinds of problems. He was also a bureaucrat who enforced regulatory policies. The only thing he did right, from a Libertarian stand, was endorse the Equal Rights Amendment, and integrate blacks into schools, though, both were not without controversy, concerning his "methods". He basically half-assed it to try and salvage his approval rating.
Herbert Hoover cannot be mentioned separate of the Revenue Act of 1932. On top of that, he used military forces led by Douglass MacArthur to stamp out a protest. That protest was comprised of WWI vets demanding that they be given what was promised to them by the government. So he's at the top of the list in my book.
I also have to mention, and I'm actually surprised that you left him out, is Ronald Reagan. This guy was pretty bad, gun control, Iran-Contra affair, turning the Russo-Afghan war into yet another American proxy, war on drugs, he violated every Libertarian principal in the book, and that's why I vote
other.
