It’s been a mere week since Senate Republicans acquitted President Trump in his impeachment trial — assuring him once and for all that he needn’t fret about congressional accountability — but he has already made significant progress on his enemies list.

Members of Congress, administration officials, law enforcement officials, residents of blue states — anyone who has ever displeased Mr. Trump is a potential target. Heads may not wind up on literal pikes, but the president is already neck-deep into his reprisal tour.

The president’s targets can be sorted into multiple different categories, some better equipped than others to endure his wrath. Democratic senators such as Mr. Jones of Alabama and Mr. Manchin of West Virginia, both of whom have drawn Trumpian ire for their votes to convict the president, understand that politics is a blood sport. Ditto House members like Ms. Dingell, whom Mr. Trump randomly attacked again over the weekend, and Mr. Schiff, who was the point person on impeachment. These professionals know how to brush off — or brush back — the taunts.

After a particularly childish screed, in which Mr. Trump called Mr. Manchin “Joe Munchkin,” the West Virginia lawmaker returned fire Monday on CNN: “I guess he’s confused on that, because I am a little bigger than him. He’s got me about 30 pounds on weight. But I am a little taller than him.”
