Canada

Tldr; Conservatives are the problem on purpose so they can blame others.

Conservatives intentionally make policy decisions which make problems worse heading into an election, or otherwise try their best to prevent others from solving the problems when not in power, so they have problems to blame the other parties on regardless of whether their policies are responsible for the problem persisting.

It's a longtime strategy of Republicans and it's been working more than people would like it to, and Canadian conservatives use it as well especially in Alberta. Before the conservatives got back in before the pandemic, they blamed the AB NDP on problems that take way longer than 4 years to solve (which they are responsible for) and got back into power. Then healthcare got worse and worse and when the pandemic hit they intentionally nulled the contract the province had with doctors and shit hit the fan, got to the point you couldn't even see a doctor outside of emergency here for minor things like getting an STI test (so prepare for there to be a lot of young people rocking crotch rot in the province unknowingly btw).

They also stomped out all the tech grants that were getting big tech companies to invest in the province so the economy would be diversified. Now what do they whine about now that the US is running back nazi policy? Oh we need to diversify to be resilient to us trade attacks. Huh who could have guessed.

Next election cycle they then blamed the federal government for the financial and healthcare problems that they themselves contributed to but also control (federal government does not control healthcare or the lack of corporate incentives in investing in a particular province) , giving taxpayer money to large corporations which in turn pay them - and funding it by cutting more public services which in turn they blame the feds on.

Conservative voters are probably one of the dumbest demographics on the earth considering they are statistically the ones who rely most on the programs and services cut by their governments.
