New York Times: “In an unusually coordinated series of attacks leveled from congressional offices and the Senate floor, in state capitols and sidewalk protests, Democrats excoriated Mr. Trump as racist and demanded that Republicans either stand behind his comments or condemn him and even rescind their endorsements of his candidacy.”

“Democrats received unexpected ammunition from Mr. Trump himself, who, in an extraordinary conference call with allies on Monday, urged them to defend his criticisms of a federal judge’s Mexican heritage — and then rebuked his campaign staff for having suggested otherwise.”

Politico: Trump train derails on Capitol Hill

First Read: “After her victories over the weekend in Puerto Rico and the Virgin Islands, Hillary Clinton is now just 19 delegates away from hitting the 2,383 magic number of delegates needed to clinch the Democratic nomination. And since she’ll easily cross it before polls even close in California (126 pledged delegates are for up grabs in New Jersey alone on June 7), here’s maybe the most important question in politics over the next month: WWBD — What Will Bernie Do?”

“Does he continue fighting all of the way through July’s Democratic convention? “The Democratic national convention will be a contested convention,” Sanders declared on Saturday, per NBC’s Danny Freeman. Or does he bow out after tomorrow’s results? And bow out gracefully?”

As one Capitol Hill Democrat closely observing the Clinton-vs.-Sanders race said: “It’s absolutely going to be the difference between a positive, proactive summer of unity and one that will lead to the same location — but travel across a much more treacherous path.”

Former Nixon speechwriter Ben Stein shared his views on Donald Trump with The Guardian. Some excerpts:

“He is not a great businessman. He inherited a great deal of money. He did some successful real estate deals. Hardly anyone could miss doing successful real estate deals in New York considering the incredible boom that has taken place and the very low base point when he started out. He is not a great businessman at all – in no way.”

“I’ll vote for him, by the way. I’ll vote for him because I think he does personify a kind of national pride which I think has been lacking in the Obama days and would be terribly lacking under Bernie Sanders and terribly lacking under Hillary Clinton. But I think his economics is way, way out of whack and he seriously needs some education about it.”

“I don’t think Trump knows a goddamn thing about economics. But I like him anyway, I might add.”
