He pointed to the election that shook Chancellor Angela Merkel's government in Germany last week in Bavaria as voters turned their backs on conservative allies against the progressive, pro-refugee Greens.
"Australians are cut off from politics as a whole, and this also reflects a broader trend in Western politics," said Roggeveen, adding that "center-left and center-right parties emerged from social and economic conditions For example, Australia's opposition Labor Party has its roots in organized work and "people are no longer joining the unions," Roggeveen said. From a conservative perspective, he said, "If the union is no longer a threat, there is far less reason for the liberals to gain support from this group of people."
George Megalogenis, an author and political commentator, said this sort of breakup could help explain Mr. Morrison's scattershot attempts to woo Wentworth's wavering liberal voters in the weeks before the election.
Mr. Morrison threw "haymakers, hoping something will connect," said Mr. Megalogenis. "You have to wonder what their instincts are when you deny the socio-economic composition of society, you can not explain otherwise."
When he tried to convince the Wentworth voters, David Sharma, the candidate of the party, Mr. Morrison promised government funds to local surf clubs and even said he might consider moving the Australian Embassy from Tel Aviv to Jerusalem, followed by President Trump. That would have broken with a decade-long policy, and the proposal brought contempt as a transparent offer for the votes of Wentworth's handsome Jewish community.
