even fewer friends

Seems Donald Trump just might be a "power freak."

He hides rejection with "I said NO."

Trump’s latest pissing on another Republican senator has jeopardized the future of his already failing legislative agenda.

The Tweet about Bob Corker on Sunday came just when Mr. Trump can’t afford to lose even one Republican, given his repeated failures on health care.

Under the normal rules of politics, a president would not poke a senator in the eye when he has only a two-seat majority, said Thomas Reynolds, Republican of New York.

Remember Trump's endorsement for Luther Strange?

How did THAT work out for Luther?

Tom Davis of Virginia said the split with Mr. Corker would undermine Trump’s influence with others. “Corker’s comments carry credibility because of his reputation,” he said. “There is an old saying in politics: Don’t pick a fight with someone who has nothing to lose.”

Trump said the retiring senator “didn’t have the guts to run” for another term.

Mr. Corker responded on Twitter an hour later, saying that the White House had become an “adult day care center.”

He then said in public what many of his Republican colleagues say in private — that the president is dangerously erratic, treats his high office like “a reality show,” has to be contained by his staff“ to prevent World War III.”

Mr. Corker, a moderate by temperament as well as ideology, had curbed his occasional criticisms of Mr. Trump for months, but has decided not to run for a third term.

Republicans made little attempt to hide their irritation at Trump for attacking Mr. Corker.

Senator Rob Portman, Republican of Ohio, said in a statement. “If we’re going to accomplish our economic and national security agenda we’re going to have to work together, period.”

“This was going to be hard no matter what,” said Billy Piper, Mr. McConnell’s former chief of staff. “Trump took one of the linchpins and incinerated him for no reason.”

The White House spent Monday claiming that Mr. Corker was responsible for the fight, not Mr. Trump. "Well HE started it!"

Mr. Trump has grown frustrated as legislation to repeal President Barack Obama’s health care program has repeatedly FAILED. He has open conflicts with Senators John McCain and Jeff Flake of Arizona, Lindsey Graham of South Carolina and Lisa Murkowski of Alaska, to name a few.

Monday, Trump went golfing.
