I have no clue what you are saying, it makes no sense. I think presidents can help relieve or create tension, Clinton and Reagan relieved tension, Obama and Trump amp up tension.
Obama being black amped up tension
Trump being an asshole amped up tension
Obama pitted the elites against those that were clinging to their guns and bibles and people against insurance companies, told Republicans to ride in back, blamed Bush and Republicans for every problem for 8 years, banks against the working class, even after bailing the banks out. At least in his second term he did tone it down some.
