Headlines screaming "Deportations to begin" and "Markets sink as trade war looms" top a parody newspaper front page the Boston Globe posted on Saturday, with a scathing editorial denouncing Republican presidential frontrunner Donald Trump's candidacy.

The mock-up, offering the Globe's satirical view of America under a Trump presidency, was set to run as the front page of the newspaper's "Ideas" section, followed on page 2 of that section by the anti-Trump editorial.

The novel front-page spoof, says the editorial, is designed to take Trump's rhetoric and his policy positions to their "logical conclusion."

"It is an exercise in taking a man at his word," the editorial says. "And his vision of America promises to be as appalling in real life as it is in black and white on the page." [...]

The editorial brands the billionaire businessman as a "demagogue" whose own political vision is "profoundly un-American."
