Is American-style Democracy sustainable given the Trump era?

This is for Discussion.
 
The way I see it is that for any Democratic country to thrive, the forces or ideals that unite them must be strong enough to withstand the forces that can divide them. What unites Americans is freedom, a government chosen by the people. Anyone of any political persuasion in the US would probably agree to this. The problem is that it may not be enough to cover or guide us through what can divide us which are the differences of opinion that will inevitably occur, even between just two people. These differences of opinion can be on morality, social issues, economic policies, immigration, etc. Politicians exploit these differences in order to stay in power and to profit from it. That's a huge problem. We have got to find some way to not politicize our differences while also increasing focus on our common values.
