if Michael Moore, Bill Maher or someone else does make this, I would be totally in support of it. But at the same time, I'd like to think I came up with this idea on my own (although it would not be surprising if others also thought of it).
Maybe a Facebook Group has already been Created?
"American Refugees from Trump Presidency?"
someone should make a documentary of Americans leaving the country per Trump's winning.
Show them talking about why they are leaving and when they are packing up, making arrangements, etc
Then show where they move to, moving, etc and interviewing them again at that point.
Then a 6 mos, 1 year, 2 years later, interview with them again.
Also maybe include any online or real-life communities or networks they may be involved with others who've done the same thing.
If I had the time and money, I would totally try and make this.
