Love him or loathe him, Mr Donald Trump is here to stay.
His status as the Republican presidential front runner was cemented with seven wins on Super Tuesday (March 1), and he has maintained his lead over rival Ted Cruz with subsequent victories in the states of Louisiana and Kentucky on Super Saturday (March 5).
With the prospect of Mr Trump taking his place as the Republican party's presidential candidate now highly likely, here's a look at what columnists from key news publications in the US and beyond are saying about the brash New York billionaire.

Donald Trump embodies how great republics meet their end

Donald the Dangerous
An apt image is conjured up by NYT's Nicholas Kristof: "Is there any scarier nightmare than President Donald J. Trump in a tense international crisis, indignant and impatient, with his sweaty finger on the nuclear trigger?"
He pointed out that most of the discussion about Mr Trump has focused on domestic policy, but checks and balances mean he can be curtailed on that front - it is abroad where the Constitution could give him a much freer hand.
Chickens, Home to Roost
The most enjoyable thing about the Trump phenomenon, according to NYT's Maureen Dowd, has been watching Mr Trump make monkeys out of a lot of people who had it coming.
Wall Street Journal
Donald Trump's Latin Role Models

Washington Post
Is this the end of the West as we know it?

"In any case, he prefers the company of dictators to that of other democrats," she wrote.
