If someone is 1900 miles west of you, they will be in (almost) your exact same physical location after a short time (about two hours). If someone is 1900 miles south of you, they won’t. So it depends on the cardinal directionality.
That being said, 1900 miles isn’t that far relative to the circumference of the earth (~25,000 miles), so someone 1900 miles south of you would see mostly the same sky. You’d each see some stars the other couldn’t see, but only near the horizon. About 85% of the sky would be the same (if you could see perfectly to every part of the horizon).
Complacency, stupidity, and ignorance. Have you ever heard a Trump supporter try to defend their positions? They haven’t thought through anything complicated in their entire lives. They believe whatever they’re told by their favorite authority figures (usually something like Fox “News”).
They’re also generally pretty bigoted. Whether that comes first or is a result of being indoctrinated into authoritarian thinking, I’m not sure. Basically, they get drunk on hate, get addicted to it, and always need their fix.
The autocratic figure promises them to fix all their problems that the [insert minority group of the week] definitely caused them. When they have no ability or desire to think critically about their claims, they just believe it. Evidence to the contrary be damned.
