Austria is holding an election on Sunday , and the immigration restrictionist candidate Norbert Hofer is polling well. The media calls him far right for having such unliberal views, but Europe is reaping what its elites, particularly German Chancellor Merkel , have sown, namely the open borders offered to the West’s 1400-year enemy of Islam.

Muslims are behaving normally, i.e. raping and pillaging among the infidels, but that barbaric conduct appears to be a surprise to the government suits in big offices. Elites imagine that historic enmity will disappear just because they want it to, even as “Rapefugees Not Welcome” signs are a common sight at citizen demonstrations.

A totally predictable result of open-borders anarchy is the growth of pro-borders patriots, such as in Germany where the AfD party made noteworthy gains in March, showing voter dissatisfaction with Merkel’s suicidal policy of inviting the hostile Muslim world.

An interesting sidebar is a recent report by the New York Times of the imported violent crime problem. Normally the paper just ignores the genuine havoc created by Muslim diversity loosed upon Europe. But a piece in Saturday’s paper took the suffering seriously and cited it as a factor in the Austrian election.

To be sure, the usual weasel words and phrases are used, like “anti-immigrant sentiment” being “whipped up” for political purposes. Still, the human cost of Merkel’s Muslim infatuation is examined by a look at the victims, particularly the grandmother who was raped by a migrant and now experiences anxiety and needs more care. The Afghan convicted of the crime received a sentence of only 20 months imprisonment because he claimed he was a minor — a common ploy among the invaders to get better treatment.

VIENNA — By any measure, the string of crimes has been terrible. A grandmother of three, walking her dog, raped along a riverbank. A 10-year-old boy sexually assaulted at a public swimming pool. A 21-year-old student gang raped near the giant Ferris wheel at Vienna’s famed Prater park. A 54-year-old woman beaten to death on the street.

The fact that the crimes were committed by recent migrants from war zones and an immigrant who had lived illegally in the country for years added an especially volatile element to the political climate ahead of the presidential election on Sunday, when Austria could become the first European country to elect a

Austria could become the first European country to elect a far-right candidate as head of state since the end of Nazism.

Nationalism and anti-immigrant sentiment had already been whipped up by the surge of refugees who streamed into Austria last year. Now, the assaults and the coverage of them in the tabloid press could help the far-right presidential candidate, Norbert Hofer of the Austria’s Freedom Party, in what appears to be a tight race against Alexander Van der Bellen, a former Green Party leader.

Sunday’s runoff between Mr. Hofer and Mr. Van der Bellen could turn on concerns that the country’s leaders lost control under the tide of refugees and migrants who reached Europe last year.

At least 90,000 people applied for asylum in this country of 8.4 million before Austria’s government shut its borders and persuaded all the Balkan states, through which the migrants trekked from Greece, to follow suit.

Since then, the challenges of integrating the refugees have become clearer as concerns about crime, sexual mores and cultural clashes come into stark relief across Europe, highlighted by the New Year’s Eve assaults on German women by Arab or North African men in Cologne.

A link between the increased numbers of asylum seekers in the country and any rise in sexual assaults and other crimes has not been established statistically, the Interior Ministry and the Vienna police say.

Over all, the agencies said, crime has declined in the Austrian capital over the past decade.The number of criminal offenses nationwide also declined, to 417,000 in 2015 from 427,000 in 2014, although a slight rise was recorded in the first quarter of this year, the Interior Ministry said.

But especially grim acts, starting with the rape of the grandmother in September, have been hashed over with increasing intensity, feeding the anti-migrant sentiment that helped propel Mr. Hofer to first place in the first round last month.

Sylvia Bubits, 54, walked a path her mother once took daily before she was raped last September.

“Is it just a feeling? Or actually the shocking reality?” the biggest-circulation daily, Kronen Zeitung, asked in early May, reporting on sex crimes and robberies in three Austrian cities. The newspaper asserted that women increasingly fear some public spaces, and questioned whether “one really cannot detect a trend in the statistics.”

Sylvia Bubits, 54, is living the conflicts dividing Austria. She is a longtime resident of Traiskirchen, the town just south of Vienna that hosts Austria’s largest center for refugees. Displaced people first arrived from the conflicts of the Cold War, then from the Balkans and now from the Middle East and beyond.

Ms. Bubits is also the daughter of the woman, now 72, who was raped while walking her dog on Sept. 1. Since the attack, Ms. Bubits said, her mother has gone from being healthy to ridden with anxiety and requiring close attention.

“It goes up and down,” Ms. Bubits said, but “it’s basically as if she was suddenly 90.”

On a visit to her home on Friday, her mother could barely shuffle a few steps without assistance. Ms. Bubits said she and her mother wanted to speak out about what had happened to emphasize that despite the problems many Austrians want to help refugees and make a place for them in their country.

According to court documents, her mother was walking her 13-year-old dog by the Schwechat, a river where refugees and residents often bathe. A young man helped her up a slope, but then, the documents said, “exploited her physical weakness,” threw her to the ground, “held her mouth shut, ripped her clothes and forced her to engage” in sex.

Despite the assault on her mother and an earlier attack in which, she said, her 22-year-old son’s nose was broken by refugees, Ms. Bubits said she remained a firm advocate for migrants. She cried with joy when she saw two 17-year-old Afghans she helped last year at a reunion at a local cafe.

“There are two sides to this question,” she said of Austria’s coping with refugees, stressing that she believes integration can work.

The man accused of attacking her mother, an Afghan who was caught some weeks later, denied his actions until D.N.A. evidence identified him. He then asserted that he had drunk a bottle of vodka beforehand and could remember little. Prosecutors said he had recalled details that only a perpetrator could have known.

At a trial in January, Judge Petra Harbich sentenced the man, who says he was born on Jan. 1, 1998, meaning he was a minor when he committed the crime, to 20 months in jail for the rape and stealing a pack of cigarettes. That sentence, while in line with treatment of minors in Austria, was ridiculed by one of Ms. Bubis’s lawyers, Dietmar Heck, as too mild.

Mr. Heck’s practice has also taken on the case of the 54-year-old woman, identified in Austria only as Maria E., who was bludgeoned to death by a homeless Kenyan man at 2:30 a.m. on May 4 outside the 24-hour sports betting shop in Vienna where she worked as a cleaner.

It has emerged that legal, bureaucratic and diplomatic hurdles prevented the police and state prosecutors from detaining or deporting the Kenyan. He is now 21 but came to Austria as a teenager to rejoin his mother, who still lives here.

The man had been detained more than a dozen times and convicted at least twice for drug dealing and other crimes. When he assaulted the cleaner, the police had requested his detention on grounds of mental instability.

A 14-member commission is investigating the case, which has fed calls for a tougher approach to foreigners who some Austrians say do not belong in the country.

Other Austrians worry that politicians are effectively asking the legal system to tackle questions that judges, lawyers and police cannot answer.

“It is all getting whipped up politically,” said Martin Mahrer, a lawyer who is defending one of three young Afghans who have confessed to raping a female Turkish student in a park on April 22. “People now want offenders to be really severely punished.”

Mr. Mahrer said some of these young migrants had arrived from war zones, with completely un-Western views about women.

“They do not respect the same things we do,” Mr. Mahrer said. But, he asked, are foreign offenders less equal before the law than Austrians?

William Spindler, a spokesman for the Office of the United Nations High Commissioner for Refugees, noted that most newly arrived refugees do not commit crimes.

“There are many examples of Afghans adapting very well to the West,” he said when asked about men from Afghanistan who are unused to seeing women alone in public, or consuming alcohol. If crimes are committed, individuals should be held to account, Mr. Spindler added.

He suggested that any group of people contained potential criminals and said the large number of arrivals last year meant that the total of such individuals could run into the hundreds for any country’s migrants.

A measure of how widespread calls for “zero tolerance” have become came in the last TV debate between the two presidential candidates. Mr. Van der Bellen said episodes like the assaults on women in Cologne required a tough response “because that is an attempt to occupy a certain public space, and that we won’t countenance.”
