... here in the US Ronald Reagan is looked at as one of the greatest presidents to have ever resided over my country.
Really? All 300 million Americans are in agreement on Ronald Reagan's greatness? I find that hard to believe when you consider the wide range of opinions on almost any other subject or person you'd care to mention.
In reality, as with most other things, there are people who think Reagan was great, people who think he was not great, and people who fall in the middle of those two extremes. Just because you think he was great doesn't mean the whole country thinks he was great.
p.s. It's "presided", not "resided". The first means "to be in charge of" and the second means "lived in".
