Does Trump's gradual lean toward the political Center help him in 2020?

[PoliticalJunkie23]

These past 8 months have shown us how erratic Trump is. But if he does the unexpected and becomes a consistently centrist/lean right President, while also toning down his rhetoric (which I can see happening as the presidency wears him down, as it does to every president), I can see his approval rating go above 50%. We need to remember that most people would like Trump and his policies if it wasn't for his personality. If he can change his personality and the way he conveys himself, he is a two termer.
