Canada

Republicans, Conservatives were Democrats.

And the Liberals were Conservatives? This was back when everyone was balancing the budget, so that adds. The Republicans of the day were respectable establishment types as well, very different from the fascist nonsense that it's become.

The rest I kind of need to argue with a bit.

Immigrants will mostly be right of the status quo because there’s more reason to leave a right wing society than a left wing.

More-or-less true, although I'd tie both back to undereducation and underdevelopment. But that's not new.

You can see that in the last election as boomers overwhelmingly voted Liberal while people under 34 voted Conservative.

Young people disproportionately voted NDP or Green, which ate into the Liberal share. Although they were all fairly split, as the chart shows.

You also see this reflected in policy as the further right you go the more immigration the party calls for.

Except this is almost never true anymore. Even PP has tried to raise a stink over immigrants, despite being in a country that's 98% immigrant and unlike the US kind of knows it.
