In a widely distributed flier, the campaign is echoing Trump’s claim last year that aggressive Muslim migration has turned some European neighborhoods into “no-go zones.” In one series of national ads, billboards in cities, towns and villages asked Hungarians, “Did you know?” before answering their own question:

“Since the beginning of the migration crisis more than 300 people died in terrorist attacks in Europe.”

“Since the beginning of the migration crisis, harassment against women in Europe increased dramatically.”

“The Paris attacks were carried out by migrants.”

Critics concede it is within the limits of freedom of expression for anti-migrant supporters to make such blanket claims. But what is extraordinary, they say, is the zeal with which the government itself has become a mouthpiece for ethnic and religious caricatures.
