Its hard to compete with a party that offers programs using debt while also cutting taxes, because a high debt load can be kicked down the road and rolled over until it reaches a crisis.
A repeat of Trudeau Sr, which caused pain during Chretien who had to cut spending and raise taxes during a recession, which had his polls fall dramatically by the end.
Caroline Rogers "rang the alarm bell" on productivity, and interest rates will be higher going forward due to aging demographics, so debt will compound faster than it had been. We also had the second to last per capita GDP growth of the 38 country in the OECD since 2015, which was below inflation.
You can import a lot of people to spread the debt amongst more people, though you'll have Trudeau's polling numbers by the end due to severe shortages of basic necessities. Trump allowed Carney to win this last election, though if the tariffs stay in place our interest rates will also rise dramatically, and we need to spend less.
