that's kind of what the USA is going through right now but it's more aptly described as "tyranny of the plurality" because Trump didn't win either majority of of registered voters or majority of the actual vote.
Regardless of tiresome partisan hyperbole, I don't regard the substance of this administration's actions as any more authoritarian the previous or the status quo. In the specific instances where state power has been expanded, I regard it as part of the general trend of expansion. The trend is more indicative of the overall incentives and structure of governance, rather than specific political actors. Similarly, partisan recriminations fit with the same pattern.
IMO, Obama claiming the power to assassinate US citizens on US soil (by declaring them "foreign combatants") was primarily different in that he only used it a little bit.
