There are signs this is the case this year. I do see the situation as a danger. The concerns that the Trump campaign should have been "put away" long ago are valid.
The U.S. has never had a demagogue like Trump nominated by a major party. The methods of fighting such a person must be different.
Hillary Clinton can still win this race. The question is whether the media will be professional and do its job, or instead succumb to the glitz of a very experienced showman.
