Which such systems have a system where ideas that are 43% or greater usually win? I want to know.

Edit: My dad says that Ukraine has such a system where 40% or more, cool.

Ones where the incumbent gets 43% and is unwilling to step down?

Uhm, what I said is that most voting systems are not that simple: eg. in USA in Trump vs Clinton, Trump won the presidency even of he won 46% of the popular vote vs 48% for Hilary: https://en.m.wikipedia.org/wiki/2016_United_States_president...

Many voting systems require a party to pass a voting threshold to get any seats. Imagine a threshold of 5%, and 10 parties each winning 4% of the vote, with one party winning 40% and another winning 20% (4% x 10 + 40% + 20%): votes for those 10 parties get discarded any you generally have 2:1 for the two winning parties, with one having 66.6% of the seats yet only winning 40% of the votes (something like that happened in Serbia ~10 years ago).
