The headline atop this blog comes from the mouth of the president of the United States.

Barack Obama said that about Republican presidential nominee Donald J. Trump.

That an incumbent president would say such a thing about a candidate who wants to succeed him is astonishing on its face. Here’s the thing, though. The president is correct.

Obama took the question today at a press conference with the Singapore president. Is Trump fit to be president? The president said the GOP nominee is “wholly unprepared” to occupy the most powerful office in the world.

But then the president got to the crux of his remarks in response to the question. When will the Republican political leadership decide it has had “enough” of Trump? he asked.

OK, it’s more or less a rhetorical question. It appears that folks such as House Speaker Paul Ryan, Senate Majority Leader Mitch McConnell and other congressional leaders have no intention — at least not yet — of taking back their endorsements.

Ryan in particular has spoken strongly against certain statements and policy positions that Trump has posited. He’s called the GOP presidential nominee’s proposal to ban Muslim immigrants a “racist” policy. He keeps insisting that he has significant policy differences with Trump.

Yet he endorses his candidacy?

Now we have the latest, the building feud between Trump and the Gold Star parents of a young Army captain who died in combat in 2004. The captain and his parents are Muslims. The parents have spoken out against Trump’s candidacy. Trump’s response to the parents’ criticism has been condemned from all corners, including from some Republicans.

That is the latest basis for President Obama’s assertion that Trump is unfit and “wholly unprepared” to become president of the United States.

When, indeed, will the leadership of the political party he is leading into political battle going to say “enough is enough”?
