Canada has had the same political current sweep across it in the last many years. The rise of the Bloc Quebecois wiped out the centrist Liberal party in Quebec, which, coupled with a few scandals, led to its virtual wipeout. The once dominant party isn’t even the opposition anymore, with the left-wing NDP taking on that role in Ottawa.
Similarly, the Labour party in the UK was rolled back due to the rise of Scottish nationalism *after* an independence referendum failed.
The result in both cases was strengthening of the Tory party.
There are even parallels between the UK election and the recent Israeli one, where disaffected right-wing voters “came home” to Likud rather than risk a principled but loss-inducing vote for Libermann or Bennett. UKIP did not achieve the results the polls predicted either in seats or in votes.
What’s the message for the United States? Potential existential threats or radical changes will force people to vote against the rest of their interests, as perceived by a certain economic view.
Democrats lament the white working class’s perceived vote against its own interests by supporting the Republican party, but sometimes this would make sense, if the threat posed by the Democrats weren’t illusory. The threat of a Labour-SNP coalition, though, meant at least radical changes in the UK itself which seems much more immediate than renegotiating the relationship between the UK and the EU.
Democrats need to, more than Republicans, make it perceived that they have a handle on global events like Iran and events at home like Baltimore. The kinds of change Democrats want, and the kinds of conflict it invites with big money elites, cannot be waged by the college faculty class alone.
The UK would be better served by tightening its trade relationship with Canada and the US rather than being sucked into the nihilistic bureaucratic nightmare that is the post-crisis EU, a union of the Germans for the Germans and by the German bankers.
