Are the Democrats too confident?
Both on and off the record, Democratic Party thinks that Hillary Clinton will win in November and victory will be huge. However the democrats realize that the argument could turn into the favor of Donald Trump because the gravitational force of these elections is a desire to change. Therefore, in this kind of environment, Clinton suffers from being the ultimate establishment figure. But the democrats still believe that forces in the favor of Clinton are stronger. If this is over-confidence then yes, Democrats are too confident.
