Great video overall, and touches two issues with our current system and culture; the act of gerrymandering has greatly skewed it so that when a million+ more people vote Democrat than Republican... the Republicans get more representation (and that's not to say that Democrats wouldn't do the exact same when they are in power) and that Democrats are backing themselves against a wall by insisting on moving to cities and Democrat counties, leaving the rural regions free for Republicans.
When people say, "Republicans are what people wanted..." just know they are full of absolute shit. And if Democrats redraw the lines in their favour and say the same, they are full of shit too. These lines should not be drawn by the people who benefit from how they are drawn. As it says in the video, "It's not the voters choosing their representatives, but the representatives choosing their voters."
