Maybe demonising major fraction of voters is not most effective tactic. Maybe you need to show that you actually did something for people in past term. Maybe you need to show that things that matter for many will get better. Say living conditions or cost of living.
I've been voting in the US since the 1990's. We've never had a presidential candidate that won and actually delivered on their promises, all of which have generally hovered around the idea that "things will be better this time." What makes you think this one will be any different?
