GOOD POINT: Trump should learn from Obama’s mistakes: A win is not a coronation, and the presidency is not the only office that matters. And, as Barack Obama never seemed to grasp, there’s always another election coming up.

For eight years, Obama pretended that his victories over John McCain and Mitt Romney somehow invalidated all opposition to his proposals. Only raw partisanship could explain his opponents’ positions because, after all, he had won.

But the Republicans who were opposing his agenda had won too. They were elected by real Americans who had real reservations about Obama’s policies. Their voices deserved to be heard. Our republican system of government was designed specifically to empower them. And yet Obama spent two entire presidential terms telling them to get lost.

And he chose . . . poorly.
