This is one of my favorite examples of President getting elected with mere 22.2%.

Chile used a system similar to states electing Governors by legislature in case of no majority (like recently in Vermont), as evident with the famous 1970 election. Allende got the first place with 36.61% (against Alessandri's 35.27%) and was then formally elected by the Congress.
Estonia uses a somewhat similar system, although an indirect one. If the President is not elected by the Parliament by 3 rounds, it goes to so-called "Electoral Body". Lennart Meri lost all parliamentary ballots, but prevailed in the latter.
