Yesterday Obama pointed out that Trump is unfit to be president.

Speaking in the East Room of the White House while Mr. Trump rallied supporters in a nearby Virginia suburb, the president noted the Republican criticism of Mr. Trump for his attacks on the Muslim parents of an American soldier, Capt. Humayun Khan, who died in Iraq.

But Mr. Obama said the political recriminations from Republicans “ring hollow” if the party’s leaders continue to support Mr. Trump’s campaign.

“The question they have to ask themselves is: If you are repeatedly having to say in very strong terms that what he has said is unacceptable, why are you still endorsing him?” Mr. Obama said. “What does this say about your party that this is your standard-bearer?”

The thing about Trump is that it’s not just his views or his policies (if he actually has anything that can really be called a policy) – it’s his nature, his character, his way of being. It’s how horrible he is in every visible way.

Has anyone come forward to say anything like, “Look, I know Trump seems rude and abrasive in public but behind the scenes he’s actually a warm, caring, decent guy”? Not that I know of. As far as I can tell what you see is exactly what you get – a rude, abrasive, belligerent asshole.

Mr. Obama lamented what he called an attack on a “Gold Star family that had made such extraordinary sacrifices on behalf of our country.” He said he did not doubt that Republicans were outraged about the statements Mr. Trump and his supporters had made about the Khan family in the last several days.

“But there has to come a point at which you say somebody who makes those kinds of statements doesn’t have the judgment, the temperament, the understanding, to occupy the most powerful position in the world,” Mr. Obama said.

The president did not limit his criticism to Mr. Trump’s treatment of the Khan family. Mr. Obama said the Republican nominee had repeatedly demonstrated that he was “woefully unprepared to do this job.” The president said Mr. Trump had proved he lacked knowledge about Europe, the Middle East and other parts of Asia.

“This isn’t a situation where you have an episodic gaffe. This is daily,” Mr. Obama added. “There has to be a point at which you say, ‘This is not somebody I can support for president of the United States, even if he purports to be a member of my party.’ The fact that that has not yet happened makes some of these denunciations ring hollow.”

As hollow as Trump himself.
