Mr Donald Trump is now the Republican Party's presumptive nominee for the US presidential election on Nov 8.
Whether the prospect of Mr Trump in the White House fills you with dread or optimism, there is no denying that the brash-talking billionaire real estate mogul has become a true force to be reckoned with.
Here's a sample of what some of the most well-respected columnists have to say about Mr Trump and how his closest rival, Texas senator Ted Cruz, failed to muster a meaningful challenge.
The Guardian
America's Trump nightmare has arrived (Lucia Graves)
Donald Trump could actually be the next president. Just let that sink in.
This is a man who actively demeans women, has encouraged violence at his campaign rallies, would ban all Muslims from entering the US and recently seemed undisturbed by an endorsement from a leader of the Ku Klux Klan. And yet Trump, a political outsider, is poised to grasp at the highest office in the land.
Donald Trump's triumph is a lesson for Europe's politicians (Simon Jenkins)
How America votes is America's business.
David Cameron was silly last December to dismiss Trump as "divisive, stupid and wrong" - not because it was inaccurate but because foreign leaders should keep their noses out of each other's domestic politics.
Trump's aides are demanding "an apology or some sort of retraction", which is the more humiliating for Cameron.
The New York Times
Ted Cruz's bitter end (Frank Bruni)
If you listened much to Ted Cruz over these last furious months, you heard him talk frequently about "the abyss," as in what this country was teetering on the edge of.
If you listened to him over these last furious hours, you heard him mention the "yawning cavern of insecurity" that motivates Donald Trump and other bullies.
The Defeat of True Conservatism (Ross Douthat)
When Donald Trump knocked first Jeb Bush and then Marco Rubio out of the Republican primary campaign, he defeated not only the candidates themselves but their common theory of what the G.O.P. should be - the idea that the party could essentially recreate George W. Bush's political program with slightly different domestic policy ideas and recreate Bush's political majority as well.
Trump and the Lord's Work (Thomas L. Friedman)
I think what's propelling Donald Trump's success more than anything is the feeling of many Americans that our politics are totally stuck.
There is an overwhelming sense of "stuckness" - and the fantasy that Trump plays to, and plays up, is that he can pull the sword from the stone and do deals. No one was more responsible for this "stuckness", though, than today's Republican Party.
Washington Post
Trump's impending nomination means it's time for a third party (Eliot A. Cohen)
It's over. Donald Trump, a man utterly unfit for the position by temperament, values and policy preferences, will be the Republican nominee for president.
He will run against Hillary Clinton, who is easily the lesser evil but is trailed by clouds of scandal and misconduct and whose party's left wing poses its own threats to liberties of speech, religion, enterprise and association. It is time for a third candidate, and probably for a third party.
Please don't mainstream Trump (E.J. Dionne Jr.)
Donald Trump's Republican primary triumph means that this cannot be a normal election. Americans who see our country as a model of tolerance, inclusion, rationality and liberty must come together across party lines to defeat him decisively.
Many forces will be at work in the coming weeks to normalize Trump - and, yes, the media will play a big role in this.
