It will be interesting to see what happens after April 2nd. It seems likely that we'll see CPC dip again, before climbing back up as we approach election day. There's a bit of an intuitive sense that the Conservatives are aligned with Trump, even if ideologically, and anger at him is getting partially directed into a rejection of the Cons.
Yeah. I think Carney is likely to push PP to "disavow" Trump because we know a chunk of PP's voters are Trump supporters and so PP is unlikely to provide a full-throated Trump rejection. Rest of Canadians would react at it as you described.
In any case, the race is very much too close for comfort at this point.
