im 100% canadian, I dont live in the US and wondering about your system.
so as i understand your political system, a president can only hold office 2 terms. in Trumps case, he served once already, does that mean he can only serve one more, or is the clock reset and he gets a shot at 8 years?
US Presidents are limited to two terms, it doesn’t matter if they are consecutive. Grover Cleveland is the only other president who has served two non-consecutive terms.
Term-limits are a relatively recent addition though, the 22nd Amendment to the Constitution was only ratified in 1951 after Franklin Roosevelt served four terms.
