What a horrendously incompetent campaign Hillary is running. Normally you would say that with incompetence like this, she should fire her entire campaign staff. But in her case, the problem starts at the top. She has never run a competent campaign, and shows no sign of starting now. She blew it against Obama, very nearly blew it against Bernie, and now is verging way too close for comfort to the edge of blowing it against Trump, which should be impossible.
Hillary is running a rather poor campaign, true enough. However, the underlying problem may not be the campaign, but rather the candidate. We shall see...
