In a stunning reversal, Donald Trump has said that perhaps not every Muslim would be banned from the U.S. if he is elected president. Among those he would allow to visit the country is London’s newly elected mayor, and first Muslim mayor, Sadiq Khan.

This comes after Khan, in an interview, said he’d like to visit the U.S. before inauguration day, just in case Trump won. Trump’s stance on Khan visiting America comes via the New York Times:

“There will always be exceptions,” Mr. Trump said when asked in an interview on Monday how his proposed ban would affect London’s mayor, Sadiq Khan.

“I was happy to see that,” Mr. Trump said of Mr. Khan’s election. “I think it’s a very good thing, and I hope he does a very good job because frankly that would be very, very good.”

Asked why, Mr. Trump said, “Because I think if he does a great job, it will really — you lead by example, always lead by example. If he does a good job and frankly if he does a great job, that would be a terrific thing.”

This exchange shouldn’t be happening, in all honesty, because in an ideal world, we wouldn’t have as the presumptive nominee a man who can’t distinguish between stopping Syrian refugees from relocating here and banning Muslims from entering the country. It’s a stupid talking point because it’s entirely unenforceable and it does nothing except open you up to these exact kinds of media attacks we can expect now that he is the nominee.

Trump can’t help but respond to anything anyone says about him, good or bad, and it is going to cause him to make a bigger and bigger fool of himself as time goes on. He is working incredibly hard to torpedo his own chances, and one can’t help but wonder if it’s all on purpose.
