See: The 2000 Presidential Election. It was Ralph Nader or Bust that year, and so we all got to enjoy watching George W. Bush seize the presidency with the help of his father's Supreme Court majority. Illegal invasion of Iraq. The drowning of New Orleans. The Great Recession. 

Donald Trump will be the result of your morality over reality. And Trump makes Bush look like Thomas Jefferson. Rather than stay up on your high horse, come on down and try to move things in the general direction of better—you know, three yards and a cloud of dust. It ain't pretty, but it's still forward.
