But Trump voters aren't the only Americans anxiously waiting for positive signals from the new administration. While Trump will never placate Democrats, there's another crucial group we'll call America's middle third who need to be assuaged.

Like every president, Trump will calibrate many of his actions according to how far he can go without losing them.
