They will get away with whatever the public allows them to in any system. Many of these countries also have military, courts and national police that have been politicized. Uncommon in mature western democracies but not the rest of the world. I do not include the US in that category yet although their SC is a big concern. They elected Trump but also fired him 4 years later and wouldn't stand for his attempted coup. For all its ugliness, the checks are still working.
