Inaugural Addresses ordinarily dwell on the art of the possible.

But one of Donald Trump’s most revealing lines on Monday was about the art of the impossible.

“Many people thought it was impossible for me to stage such a historic political comeback,” said 45 as he morphed into 47. “But as you see today, here I am. The American people have spoken.”

Here I am. It was both a boast and a warning.

When the reality show star burst onto the political scene in 2015, flouting all the rules, he was regarded as a clown by some and a dilemma by others, including many Republicans.

When he was elected in 2016, many assumed he was an anomaly, a deviation from the new political movement that Barack Obama represented.

But now it is the Obama coalition that looks like the anomaly and Trump who is the page-turning force in history.

He’s riding back into town as master and commander of the entire fleet, with de facto control over all three branches of government, with Republicans more compliant than ever and Democrats helpless in the face of his dominance. Trump has them all just where he wants them.
