If anyone has been campaigning to be Donald Trump's running mate it is Newt Gingrich.  He even had backing from casino mogul Sheldon Adelson, who had just pledged a reported $100 million to help Trump's campaign and get a high level job for the former speaker of the House. 

But that all apparently came crashing down on Sunday when Gingrich had the audacity to criticize the Donald's racist attacks on a federal judge hearing a case involving one of Trump's many failed enterprises.

The megalomaniacal real estate developer wants an Indiana-born judge removed from a case involving Trump University because of his Mexican heritage. 

"We're building a wall," said Trump to justify his racist attacks.  "He's a Mexican."

Actually the judge isn't a Mexican, he's as American as the second-generation developer whose Drumpf immigrant grandfather came here from Kallstadt, Germany, which is famous for its stuffed pig's stomach. As for that wall, don't hold your breath waiting for Congress to shell out the billions Donald says it will cost.

Gingrich said the attack on Judge Gonzalo Curiel was "inexcusable." 

The thin-skinned Trump, who has shown zero tolerance for criticism and usually retaliates with curses and attacks, was somewhat reserved when he called Gingrich's comments "inappropriate."

"This is one of the worst mistakes Trump has made, and I think it's inexcusable," Gingrich said on a Sunday talk show. "This judge was born in Indiana. He is an American, period. When you come to America, you get to become an American."

Gingrich wasn't the only critic – though maybe the only one running for vice president – to rebuke Trump.  Similar thoughts were expressed by Senate Majority Leader Mitch McConnell (R-Kentucky), Senate Foreign Relations Committee Chairman Bob Corker (R-Tennessee), House Speaker Paul Ryan (R-Wisconsin), Gov. John Kasich (R-Ohio).

In case you want to hear what they said, Hillary Clinton's campaign collected the sound bites and shared them with the world on YouTube.
