Odd that.
A Robert Heinlein series featuring a character named Lazarus Long had as part of its story line a similar thing happen in 2016. The then ‘president’ essentially took control and became ‘President for Life’ and cancelled the 2016 elections................
That was from the short novel, "If This Goes On", published in 1940.

The story is set in a future theocratic American society, ruled by the latest in a series of fundamentalist Christian Prophets. The First Prophet was Nehemiah Scudder, a backwoods preacher turned President (elected in 2012), then dictator (no elections were held in 2016 or later).
