Question: Why is the Left going crazy about Donald Trump's refusal to say that he will accept the outcome of the 2016 presidential election?
Answer: The Left recalls its efforts to delegitimize the presidency of George W. Bush. From the moment the Supreme Court of the United States handed down its decision in Bush v. Gore (2000), the Left refused to accept him as its president. For eight years, the Left did everything possible to mock, vilify, and obstruct him. The worst fear of the Left is that the same thing will happen to Hillary Clinton. Leftists want her to advance the progressive agenda, and they know that this will require collaboration from Republicans. If Trump and his followers do to her what the Left did to Bush, she will accomplish only a fraction of what they want accomplished. So they vilify Trump, hoping thereby to deter him (and his followers) from delegitimizing Clinton the way they delegitimized Bush.
