Rick Klein: “All conventional wisdom about how a politician responds to a terrorist attack or a mass shooting had gone out the window with Trump’s first series of Tweets, where he accepted congratulations for being right and called on President Obama to resign from office. Before Trump started speaking in New Hampshire, he had suggested that the president secretly might want ISIS to succeed. By the time he was done, he had misled his audience about the Orlando shooter’s birth status, and expanded his proposed Muslim ban to include all immigration from parts of the world with established ties to terrorism.”

“At some point, the talk about a new Donald Trump, or a reined in Donald Trump, or a ‘presidential’ Donald Trump – all of it will fade away. What’s left is a man who has played to the anger and fears of the American people to astounding effect, and apparently won’t stop until he’s either elected, or not.”

Nate Cohn: “According to an Upshot analysis of Pew Research data, nearly half of white working-class Democrats think it’s more important to protect gun rights than to control gun ownership. That’s a larger percentage of Democratic voters than agree with Mr. Trump on many of the other issues that he stresses on the campaign trail.”

“At the same time, Mr. Trump’s position has considerable support from Republican-leaning voters. About three-quarters of Republican-leaning voters side with gun rights over gun control, according to the Pew data.”

“That’s even better for Mr. Trump than a lot of his other populist wedge issues, like trade and immigration. It’s about as good as any issue for Republicans — even general conservative attitudes such as whether the government is wasteful.”

Donald Trump “left little doubt on Monday that he intends to run on the same incendiary proposals on immigration and terrorism that animated his primary campaign, using his first speech after the massacre in Orlando, Fla., to propose sweeping measures against Muslims that paid little heed to American traditions of pluralism,” the New York Times reports.

“Without distinguishing between mainstream Muslims and Islamist terrorists, Mr. Trump suggested that all Muslim immigrants posed potential threats to America’s security and called for a ban on migrants from any part of the world with ‘a proven history of terrorism’ against the United States or its allies. He also insinuated that American Muslims were all but complicit in acts of domestic terrorism for failing to report attacks in advance, asserting without evidence that they had warnings of shootings like the one in Orlando.”

Donald Trump is rescinding the Washington Post’s credentials to cover his campaign events, Politico reports.

Said Trump: “Based on the incredibly inaccurate coverage and reporting of the record setting Trump campaign, we are hereby revoking the press credentials of the phony and dishonest Washington Post.”

Donald Trump called Mitt Romney “a sad, pathetic loser who should go into retirement,” BuzzFeed reports.

Said Trump: “Romney’s a loser. He lost the election badly. He should have won that election. That election was easier than this election. He should have won that election. He choked. He was a choker. And I was very tough on him at the beginning, because we don’t want to give a choker, I backed him, but we don’t want to give a choker a second chance. We can’t afford to. He wasn’t going to win anyway. He would have choked the same way. Whatever happened he was way off.”

Ryan Lizza: “Trump had put countless Republican lawmakers in excruciating political predicaments. Senator John McCain, who told me last summer that Trump had ‘fired up the crazies,’ now needs Trump’s voters to support his own reëlection in Arizona—a state that Trump won by twenty-two percentage points in the primaries—and has said that he will support him. Marco Rubio, whose last days as a Presidential candidate were spent mocking the size of Trump’s hands and the orange hue of his face, recently apologized for the personal attacks, and said that he would speak on Trump’s behalf at the Convention.”

“Governor Chris Christie, of New Jersey, another of Trump’s opponents early in the campaign, has transformed himself into a sort of manservant, who is constantly with Trump at events. (One Republican told me that a friend of his on the Trump campaign used Snapchat to send him a video of Christie fetching Trump’s McDonald’s order.)”

“We’re being led by a man who either is not tough, not smart or has something else in mind.”

— Donald Trump, in an interview on Fox News, after the Orlando massacre that killed 50 people.

Wall Street Journal: “The two functioning stop-Trump groups remain small and have no funding behind them. One is composed of a handful of Washington-based operatives, attorneys and media personalities. The other is a coalition of about 15 convention delegates from Colorado who are trying to gather support for a rule that would unbind delegates who are now mandated by various state-party rules to back Mr. Trump for the nomination.”

“Yet time, distance and disorganization are likely to render them ineffective, as the rest of the Republican Party, some with equal trepidation about Mr. Trump, steadily move toward the nomination of the New York businessman.”

House Speaker Paul Ryan (R-WI) “is dismissing efforts to block Donald Trump from formally accepting the Republican nomination at the party’s convention next month in Cleveland, saying the presumptive nominee won fair and square,” Politico reports.

Ryan told ABC News, “Seventeen people competed, one person won and he got the delegates. The delegates ultimately decide these things, but he won fair and square.”

Carl Cannon: “I’ve only met the man once, and if one of my friends wrote this column, I’d tease him about going all Gail Sheehy — I don’t usually cotton to journalists who psychoanalyze their subjects. But I believe that Donald Trump, the man who famously disparages ‘losers,’ knows deep down he isn’t equipped to be president.”

“Let’s call this more reflective subconscious entity ‘Don Trump.'”

“Donald Trump loves winning and hates losing, while Don Trump knows that running a smart campaign and beating Hillary Clinton means he’d inherit a job he has neither the qualifications nor the temperament to perform successfully. Don Trump wants to lose. He wants this campaign to be over so Donald Trump can go back to doing what he’s good at: promoting his personal brand and counting his money.”

Associated Press: “In the dozen or so states most likely to determine the race, Trump has made little progress building a campaign operation to match Clinton’s sophisticated get-out-the-vote machine. At the same time, he’s created new problems in Florida, Colorado and Nevada with comments that Republican leaders decry as racist.”

“There is a path for the billionaire real estate mogul and reality TV star to find his way to 270. But it’s narrow, given the map’s opening tilt toward the Democratic Party, and hinges on Trump’s ability to continue to defy political norms.”

“Trump will need to turn out white voters in the Upper Midwest in numbers that far exceed those in past presidential elections. Even if that happens, he’s still likely to need to convince women in swing-voting suburbs that he has the temperament to be commander in chief. And he must stop his party from losing more ground among minorities, particularly Hispanics.”
