I know it's kind of a problematic topic for a few reasons, but I had hoped the example I gave might set the tone. Jackson is (for some reason) seen as good, but there's the really obvious Trail of Tears shenanigans/murder. Maybe this is more of a trivia thread.
Let's go with Wikipedia's aggregate top 20 or so:

Theodore Roosevelt
Thomas Jefferson

John F. Kennedy
Barack Obama
James K. Polk
Lyndon B. Johnson
James Madison
John Adams
Ronald Reagan
James Monroe
Bill Clinton
William McKinley
Grover Cleveland
Abraham Lincoln - He limited free speech and appointed politically connected men to be generals, who sucked.
Franklin D. Roosevelt - More going after the press, Jap camps, and he was married to a distant cousin. He was also pen pals with Mussolini.
George Washington - Besides owning slaves, he conned his men during the French-Indian war out of something like 20,000 acres of land.
Theodore Roosevelt - A charlatan that used his connections to force himself and the US into a war that got a lot of Americans killed under his command because he sucked.
Thomas Jefferson - Dude had slaves and raped his slaves.
Harry S. Truman - Was a huge player in creating Israel and ramping up the cold war. Started the Korean War without congressional approval and then tried to blame his generals for it.
Woodrow Wilson - Huge racist. He re-segregated what little desegregation had occurred in the Federal Government.
Dwight D. Eisenhower - Another huge player making the cold war what it was. Racist also and didn't give a shit about McCarthyism spiraling out of control or the civil rights movement.
Andrew Jackson - Well this guy was obviously an asshole, huge racist, trail of tears, etc.
John F. Kennedy - Fucked bitches and hos all day. It was a problem. He was also majorly responsible for our failed foreign policy in Vietnam and got the ball rolling in Iraq supporting a Baathist coup.
Barack Obama - Drones, wishy washy interventionist policy.
James K. Polk - Huge prick to the Mexicans and the Indians. Just as racist as anyone else.
Lyndon B. Johnson - Vietnam, also he basically was overwhelmed with the job and just quit. Racist womanizer.
James Madison - War of 1812. Fucking idiot.
John Adams - Probably one of the biggest assholes to ever be President. Slave owner, authoritarian, prick.
Ronald Reagan - This guy was really terrible. Supplied Saddam weapons while he was busy gassing Kurds. Supplied weapons to everyone who is shooting at us today basically. Negotiated with terrorists. Invaded countries with democratically elected governments in South America. Huge douche bag.
James Monroe - Murdered Indians and stole Florida
Bill Clinton - Besides fucking almost as many hos as JFK, he bombed Sudan and that was bad.
William McKinley - He decided we should own Hawaii and the Philippines just because.
Grover Cleveland - He killed Americans on strike with Federal troops
