Are you equivalencing elections in Nazi Germany & Communist Cuba with US elections? Then you have just made yourself illogical.
In case you do not understand, only elections in democracies count. Cuba, Nazi Germany, Saddam’s Iraq & USSR were not democracies.
No, I was merely demonstrating the untruth of your statement "dictators are NEVER elected".
Having made this rash and unthinking statement you are backpedalling and trying to put more conditions on it than you started with. You didn't have these conditions up front, and you might admit that there is a generous amount of observer bias in deciding what is a "good" election vs. a "bad" election.
As an American I certainly want to believe that our elections are "good", although I need only look at the fraud in many elections and I can find lots of reasons why US elections might not be the gold standard we think they are. Go back 50 years and Kennedy's victory over Nixon in 1960 was almost certainly fraudulent with Chicago producing as many Dem votes as necessary for Kennedy to win. The Gore people tried hard to steal the 2000 election.
Go back to Nazi Germany, and as much as you might not want to agree, it is obvious that a majority of voters ended up supporting Hitler. This was a German election. As much as the rest of the world didn't like the result, it was a German decision to make.
Same with Castro in Cuba. At least at the beginning, more ordinary people wanted him than wanted his predecessor.
Lastly, you need to read a good civics book. The US is not a democracy, despite what the evening news says. We are a Republic, that pesky old Constitution says so, and it is true.
