Krugman's endorsement is a tremendous negative to what he endorses on the great weakness of his reputation among rational thinking people.

Hearing a dog bark makes more sense than anything Krugman says. Trump is more serious about this campaign than I originally gave him credit for. I still don't think he will get the nod but I am still listening to everybody...well, maybe not Lindsey Graham.

I think the title is deceiving.

"So am I saying that Mr. Trump is better and more serious than he’s given credit for being? Not at all — he is exactly the ignorant blowhard he seems to be. It’s when it comes to his rivals that appearances can be deceiving. Some of them may come across as reasonable and thoughtful, but in reality they are anything but."

Krugman thinks Trump is right? That should be the final nail in his coffin. Krugman's never been right about anything.
